DESCRIPTION
The LDAP protocol is defined in the following RFCs
Core LDAP Specification
RFC-4510 Lightweight Directory Access Protocol (LDAP): Technical Specification Road Map
http://www.ietf.org/rfc/rfc4510.txt
The Lightweight Directory Access Protocol (LDAP) is an Internet protocol for accessing distributed
directory services that act in accordance with X.500 data and service models. This document provides a
road map of the LDAP Technical Specification.
RFC-4511 Lightweight Directory Access Protocol (LDAP): The Protocol
http://www.ietf.org/rfc/rfc4511.txt
This document describes the protocol elements, along with their semantics and encodings, of the
Lightweight Directory Access Protocol (LDAP). LDAP provides access to distributed directory services
that act in accordance with X.500 data and service models. These protocol elements are based on those
described in the X.500 Directory Access Protocol (DAP).
RFC-4512 Lightweight Directory Access Protocol (LDAP): Directory Information Models
http://www.ietf.org/rfc/rfc4512.txt
The Lightweight Directory Access Protocol (LDAP) is an Internet protocol for accessing distributed
directory services that act in accordance with X.500 data and service models. This document describes
the X.500 Directory Information Models, as used in LDAP.
RFC-4513 Lightweight Directory Access Protocol (LDAP): Authentication Methods and Security Mechanisms
http://www.ietf.org/rfc/rfc4513.txt
This document describes authentication methods and security mechanisms of the Lightweight Directory
Access Protocol (LDAP). This document details establishment of Transport Layer Security (TLS) using the
StartTLS operation.
This document details the simple Bind authentication method including anonymous, unauthenticated, and
name/password mechanisms and the Simple Authentication and Security Layer (SASL) Bind authentication
method including the EXTERNAL mechanism.
This document discusses various authentication and authorization states through which a session to an
LDAP server may pass and the actions that trigger these state changes.
RFC-4514 Lightweight Directory Access Protocol (LDAP): String Representation of Distinguished Names
http://www.ietf.org/rfc/rfc4514.txt
The X.500 Directory uses distinguished names (DNs) as primary keys to entries in the directory. This
document defines the string representation used in the Lightweight Directory Access Protocol (LDAP) to
transfer distinguished names. The string representation is designed to give a clean representation of
commonly used distinguished names, while being able to represent any distinguished name.
RFC-4515 Lightweight Directory Access Protocol (LDAP): String Representation of Search Filters
http://www.ietf.org/rfc/rfc4515.txt
Lightweight Directory Access Protocol (LDAP) search filters are transmitted in the LDAP protocol using a
binary representation that is appropriate for use on the network. This document defines a human-readable
string representation of LDAP search filters that is appropriate for use in LDAP URLs (RFC 4516) and in
other applications.
RFC-4516 Lightweight Directory Access Protocol (LDAP): Uniform Resource Locator
http://www.ietf.org/rfc/rfc4516.txt
This document describes a format for a Lightweight Directory Access Protocol (LDAP) Uniform Resource
Locator (URL). An LDAP URL describes an LDAP search operation that is used to retrieve information from
an LDAP directory, or, in the context of an LDAP referral or reference, an LDAP URL describes a service
where an LDAP operation may be progressed.
RFC-4517 Lightweight Directory Access Protocol (LDAP): Syntaxes and Matching Rules
http://www.ietf.org/rfc/rfc4517.txt
Each attribute stored in a Lightweight Directory Access Protocol (LDAP) directory, whose values may be
transferred in the LDAP protocol, has a defined syntax that constrains the structure and format of its
values. The comparison semantics for values of a syntax are not part of the syntax definition but are
instead provided through separately defined matching rules. Matching rules specify an argument, an
assertion value, which also has a defined syntax. This document defines a base set of syntaxes and
matching rules for use in defining attributes for LDAP directories.
RFC-4518 Lightweight Directory Access Protocol (LDAP): Internationalized String Preparation
http://www.ietf.org/rfc/rfc4518.txt
The previous Lightweight Directory Access Protocol (LDAP) technical specifications did not precisely
define how character string matching is to be performed. This led to a number of usability and
interoperability problems. This document defines string preparation algorithms for character-based
matching rules defined for use in LDAP.
RFC-4519 Lightweight Directory Access Protocol (LDAP): Schema for User Applications
http://www.ietf.org/rfc/rfc4519.txt
This document is an integral part of the Lightweight Directory Access Protocol (LDAP) technical
specification. It provides a technical specification of attribute types and object classes intended for
use by LDAP directory clients for many directory services, such as White Pages. These objects are widely
used as a basis for the schema in many LDAP directories. This document does not cover attributes used
for the administration of directory servers, nor does it include directory objects defined for specific
uses in other documents.
Other LDAP Related RFCs - Proposed Standards
RFC-6171 The Lightweight Directory Access Protocol (LDAP) Don't Use Copy Control
http://www.ietf.org/rfc/rfc6171.txt
This document defines the Lightweight Directory Access Protocol (LDAP) Don't Use Copy control extension
which allows a client to specify that copied information should not be used in providing service. This
control is based upon the X.511 dontUseCopy service control option.
RFC-5020 The Lightweight Directory Access Protocol (LDAP) entryDN Operational Attribute
http://www.ietf.org/rfc/rfc5020.txt
This document describes the LDAP/X.500 'entryDN' operational attribute. The attribute provides a copy of
the entry's distinguished name for use in attribute value assertions.
RFC-4792 Encoding Instructions for the Generic String Encoding Rules (GSER)
http://www.ietf.org/rfc/rfc4792.txt
Abstract Syntax Notation One (ASN.1) defines a general framework for annotating types in an ASN.1
specification with encoding instructions that alter how values of those types are encoded according to
ASN.1 encoding rules. This document defines the supporting notation for encoding instructions that apply
to the Generic String Encoding Rules (GSER), and in particular defines an encoding instruction to provide
a machine-processable representation for the declaration of a GSER ChoiceOfStrings type.
RFC-4532 Lightweight Directory Access Protocol (LDAP) Who am I? Operation
http://www.ietf.org/rfc/rfc4532.txt
This specification provides a mechanism for Lightweight Directory Access Protocol (LDAP) clients to
obtain the authorization identity the server has associated with the user or application entity. This
mechanism is specified as an LDAP extended operation called the LDAP "Who am I?" operation.
RFC-4530 Lightweight Directory Access Protocol (LDAP) entryUUID Operational Attribute
http://www.ietf.org/rfc/rfc4530.txt
This document describes the LDAP/X.500 'entryUUID' operational attribute and associated matching rules
and syntax. The attribute holds a server-assigned Universally Unique Identifier (UUID) for the object.
Directory clients may use this attribute to distinguish objects identified by a distinguished name or to
locate an object after renaming.
RFC-4528 Lightweight Directory Access Protocol (LDAP) Assertion Control
http://www.ietf.org/rfc/rfc4528.txt
This document defines the Lightweight Directory Access Protocol (LDAP) Assertion Control, which allows a
client to specify that a directory operation should only be processed if an assertion applied to the
target entry of the operation is true. It can be used to construct "test and set", "test and clear", and
other conditional operations.
RFC-4527 Lightweight Directory Access Protocol (LDAP) Read Entry Controls
http://www.ietf.org/rfc/rfc4527.txt
This document specifies an extension to the Lightweight Directory Access Protocol (LDAP) to allow the
client to read the target entry of an update operation. The client may request to read the entry before
and/or after the modifications are applied. These reads are done as an atomic part of the update
operation.
RFC-4526 Lightweight Directory Access Protocol (LDAP) Absolute True and False Filters
http://www.ietf.org/rfc/rfc4526.txt
This document extends the Lightweight Directory Access Protocol (LDAP) to support absolute True and False
filters based upon similar capabilities found in X.500 directory systems. The document also extends the
String Representation of LDAP Search Filters to support these filters.
RFC-4524 COSINE LDAP/X.500 Schema
http://www.ietf.org/rfc/rfc4524.txt
This document provides a collection of schema elements for use with the Lightweight Directory Access
Protocol (LDAP) from the COSINE and Internet X.500 pilot projects.
RFC-4523 Lightweight Directory Access Protocol (LDAP) Schema Definitions for X.509 Certificates
http://www.ietf.org/rfc/rfc4523.txt
This document describes schema for representing X.509 certificates, X.521 security information, and
related elements in directories accessible using the Lightweight Directory Access Protocol (LDAP). The
LDAP definitions for these X.509 and X.521 schema elements replace those provided in RFCs 2252 and 2256.
RFC-4522 Lightweight Directory Access Protocol (LDAP): The Binary Encoding Option
http://www.ietf.org/rfc/rfc4522.txt
Each attribute stored in a Lightweight Directory Access Protocol (LDAP) directory has a defined syntax
(i.e., data type). A syntax definition specifies how attribute values conforming to the syntax are
normally represented when transferred in LDAP operations. This representation is referred to as the
LDAP-specific encoding to distinguish it from other methods of encoding attribute values. This document
defines an attribute option, the binary option, that can be used to specify that the associated attribute
values are instead encoded according to the Basic Encoding Rules (BER) used by X.500 directories.
RFC-4370 Lightweight Directory Access Protocol (LDAP) Proxied Authorization Control
http://www.ietf.org/rfc/rfc4370.txt
This document defines the Lightweight Directory Access Protocol (LDAP) Proxy Authorization Control. The
Proxy Authorization Control allows a client to request that an operation be processed under a provided
authorization identity instead of under the current authorization identity associated with the
connection.
RFC-4104 Policy Core Extension Lightweight Directory Access Protocol Schema (PCELS)
http://www.ietf.org/rfc/rfc4104.txt
This document defines a number of changes and extensions to the Policy Core Lightweight Directory Access
Protocol (LDAP) Schema (RFC 3703) based on the model extensions defined by the Policy Core Information
Model (PCIM) Extensions (RFC 3460). These changes and extensions consist of new LDAP object classes and
attribute types. Some of the schema items defined in this document re-implement existing concepts in
accordance with their new semantics introduced by RFC 3460. The other schema items implement new
concepts, not covered by RFC 3703. This document updates RFC 3703.
RFC-3928 Lightweight Directory Access Protocol (LDAP) Client Update Protocol (LCUP)
http://www.ietf.org/rfc/rfc3928.txt
This document defines the Lightweight Directory Access Protocol (LDAP) Client Update Protocol (LCUP).
The protocol is intended to allow an LDAP client to synchronize with the content of a directory
information tree (DIT) stored by an LDAP server and to be notified about the changes to that content.
RFC-3909 Lightweight Directory Access Protocol (LDAP) Cancel Operation
http://www.ietf.org/rfc/rfc3909.txt
This specification describes a Lightweight Directory Access Protocol (LDAP) extended operation to cancel
(or abandon) an outstanding operation. Unlike the LDAP Abandon operation, but like the X.511 Directory
Access Protocol (DAP) Abandon operation, this operation has a response which provides an indication of
its outcome.
RFC-3876 Returning Matched Values with the Lightweight Directory Access Protocol version 3 (LDAPv3)
http://www.ietf.org/rfc/rfc3876.txt
This document describes a control for the Lightweight Directory Access Protocol version 3 that is used to
return a subset of attribute values from an entry. Specifically, only those values that match a "values
return" filter. Without support for this control, a client must retrieve all of an attribute's values
and search for specific values locally.
RFC-3866 Language Tags and Ranges in the Lightweight Directory Access Protocol (LDAP)
http://www.ietf.org/rfc/rfc3866.txt
It is often desirable to be able to indicate the natural language associated with values held in a
directory and to be able to query the directory for values which fulfill the user's language needs. This
document details the use of Language Tags and Ranges in the Lightweight Directory Access Protocol (LDAP).
RFC-3727 ASN.1 Module Definition for the LDAP and X.500 Component Matching Rules
http://www.ietf.org/rfc/rfc3727.txt
This document updates the specification of the component matching rules for Lightweight Directory Access
Protocol (LDAP) and X.500 directories (RFC3687) by collecting the Abstract Syntax Notation One (ASN.1)
definitions of the component matching rules into an appropriately identified ASN.1 module so that other
specifications may reference the component matching rule definitions from within their own ASN.1 modules.
RFC-3703 Policy Core Lightweight Directory Access Protocol (LDAP) Schema
http://www.ietf.org/rfc/rfc3703.txt
This document defines a mapping of the Policy Core Information Model to a form that can be implemented in
a directory that uses Lightweight Directory Access Protocol (LDAP) as its access protocol. This model
defines two hierarchies of object classes: structural classes representing information for representing
and controlling policy data as specified in RFC 3060, and relationship classes that indicate how
instances of the structural classes are related to each other. Classes are also added to the LDAP schema
to improve the performance of a client's interactions with an LDAP server when the client is retrieving
large amounts of policy-related information. These classes exist only to optimize LDAP retrievals: there
are no classes in the information model that correspond to them.
RFC-3698 Lightweight Directory Access Protocol (LDAP): Additional Matching Rules
http://www.ietf.org/rfc/rfc3698.txt
This document provides a collection of matching rules for use with the Lightweight Directory Access
Protocol (LDAP). As these matching rules are simple adaptations of matching rules specified for use with
the X.500 Directory, most are already in wide use.
RFC-3687 Lightweight Directory Access Protocol (LDAP) and X.500 Component Matching Rules
http://www.ietf.org/rfc/rfc3687.txt
The syntaxes of attributes in a Lightweight Directory Access Protocol (LDAP) or X.500 directory range
from simple data types, such as text string, integer, or Boolean, to complex structured data types, such
as the syntaxes of the directory schema operational attributes. Matching rules defined for the complex
syntaxes usually only provide the most immediately useful matching capability. This document defines
generic matching rules that can match any user selected component parts in an attribute value of any
arbitrarily complex attribute syntax.
RFC-3672 Subentries in the Lightweight Directory Access Protocol (LDAP)
http://www.ietf.org/rfc/rfc3672.txt
In X.500 directories, subentries are special entries used to hold information associated with a subtree
or subtree refinement. This document adapts X.500 subentries mechanisms for use with the Lightweight
Directory Access Protocol (LDAP).
RFC-3671 Collective Attributes in the Lightweight Directory Access Protocol (LDAP)
http://www.ietf.org/rfc/rfc3671.txt
X.500 collective attributes allow common characteristics to be shared between collections of entries.
This document summarizes the X.500 information model for collective attributes and describes use of
collective attributes in LDAP (Lightweight Directory Access Protocol). This document provides schema
definitions for collective attributes for use in LDAP.
RFC-3296 Named Subordinate References in Lightweight Directory Access Protocol (LDAP) Directories
http://www.ietf.org/rfc/rfc3296.txt
This document details schema and protocol elements for representing and managing named subordinate
references in Lightweight Directory Access Protocol (LDAP) Directories.
RFC-3062 LDAP Password Modify Extended Operation
http://www.ietf.org/rfc/rfc3062.txt
The integration of the Lightweight Directory Access Protocol (LDAP) and external authentication services
has introduced non-DN authentication identities and allowed for non-directory storage of passwords. As
such, mechanisms which update the directory (e.g., Modify) cannot be used to change a user's password.
This document describes an LDAP extended operation to allow modification of user passwords which is not
dependent upon the form of the authentication identity nor the password storage mechanism used.
RFC-2891 LDAP Control Extension for Server Side Sorting of Search Results
http://www.ietf.org/rfc/rfc2891.txt
This document describes two LDAPv3 control extensions for server side sorting of search results. These
controls allows a client to specify the attribute types and matching rules a server should use when
returning the results to an LDAP search request. The controls may be useful when the LDAP client has
limited functionality or for some other reason cannot sort the results but still needs them sorted. Other
permissible controls on search operations are not defined in this extension.
RFC-2849 The LDAP Data Interchange Format (LDIF) - Technical Specification
http://www.ietf.org/rfc/rfc2849.txt
This document describes a file format suitable for describing directory information or modifications made
to directory information. The file format, known as LDIF, for LDAP Data Interchange Format, is typically
used to import and export directory information between LDAP-based directory servers, or to describe a
set of changes which are to be applied to a directory.
RFC-2831 Using Digest Authentication as a SASL Mechanism
http://www.ietf.org/rfc/rfc2831.txt
This specification defines how HTTP Digest Authentication can be used as a SASL [RFC 2222] mechanism for
any protocol that has a SASL profile. It is intended both as an improvement over CRAM-MD5 [RFC 2195] and
as a convenient way to support a single authentication mechanism for web, mail, LDAP, and other
protocols.
RFC-2739 Calendar Attributes for vCard and LDAP
http://www.ietf.org/rfc/rfc2739.txt
When scheduling a calendar entity, such as an event, it is a prerequisite that an organizer has the
calendar address of each attendee that will be invited to the event. Additionally, access to an
attendee's current "busy time" provides an a priori indication of whether the attendee will be free to
participate in the event. In order to meet these challenges, a calendar user agent (CUA) needs a
mechanism to locate individual user's calendar and free/busy time. This memo defines three mechanisms for
obtaining a URI to a user's calendar and free/busy time. These include:
RFC-2589 Extensions for Dynamic Directory Services
http://www.ietf.org/rfc/rfc2589.txt
LDAP supports lightweight access to static directory services, allowing relatively fast search and update
access. Static directory services store information about people that persists in its accuracy and value
over a long period of time. Dynamic directory services are different in that they store information about
people that only persists in its accuracy and value while people are online. Though the protocol
operations and attributes used by dynamic directory services are similar to the ones used for static
directory services, clients that are bound to a dynamic directory service need to periodically refresh
their presence at the server to keep directory entries from getting stale in the presence of client
application crashes. A flow control mechanism from the server is also described that allows a server to
inform clients how often they should refresh their presence.
RFC-2559 Internet X.509 Public Key Infrastructure Operational Protocols - LDAPv2
http://www.ietf.org/rfc/rfc2559.txt
The protocol described in this document is designed to satisfy some of the operational requirements
within the Internet X.509 PKI. Specifically, this document addresses requirements to provide access to
PKI repositories for the purposes of retrieving PKI information and managing that same information. The
mechanism described in this document is based on the LDAPv2, defined in RFC 1777, defining a profile of
that protocol for use within the PKIX and updates encodings for certificates and revocation lists from
RFC 1778. Additional mechanisms addressing PKIX operational requirements are specified in separate
documents.
RFC-2247 Using Domains in LDAP/X.500 Distinguished Names
http://www.ietf.org/rfc/rfc2247.txt
LDAP uses X.500-compatible distinguished names for providing unique identification of entries. This
document defines an algorithm by which a name registered with the Internet Domain Name Service can be
represented as an LDAP distinguished name.
RFC-2222 Simple Authentication and Security Layer (SASL)
http://www.ietf.org/rfc/rfc2222.txt
This document describes a method for adding authentication support to connection-based protocols. To use
this specification, a protocol includes a command for identifying and authenticating a user to a server
and for optionally negotiating protection of subsequent protocol interactions. If its use is negotiated,
a security layer is inserted between the protocol and the connection. This document describes how a
protocol specifies such a command, defines several mechanisms for use by the command, and defines the
protocol used for carrying a negotiated security layer over the connection.
RFC-2218 A Common Schema for the Internet White Pages Service
http://www.ietf.org/rfc/rfc2218.txt
This IETF Integrated Directory Services(IDS) Working Group proposes a standard specification for a simple
Internet White Pages service by defining a common schema for use by the various White Pages servers. This
schema is independent of specific implementations of the White Pages service. This document specifies the
minimum set of core attributes of a White Pages entry for an individual and describes how new objects
with those attributes can be defined and published. It does not describe how to represent other objects
in the White Pages service. Further, it does not address the search sort expectations within a particular
service.
RFC-2164 Use of an X.500/LDAP directory to support MIXER address mapping
http://www.ietf.org/rfc/rfc2164.txt
MIXER (RFC 2156) defines an algorithm for use of a set of global mapping between X.400 and RFC 822
addresses. This specification defines how to represent and maintain these mappings (MIXER Conformant
Global Address Mappings of MCGAMs) in an X.500 or LDAP directory. Mechanisms for representing OR Address
and Domain hierarchies within the DIT. These techniques are used to define two independent subtrees in
the DIT, which contain the mapping information.
RFC-2079 Definition of an X.500 Attribute Type and an Object Class to Hold Uniform Resource Identifiers
http://www.ietf.org/rfc/rfc2079.txt
URLs are being widely used to specify the location of Internet resources. There is an urgent need to be
able to include URLs in directories that conform to the LDAP and X.500 information models, and a desire
to include other types of URIs as they are defined. A number of independent groups are already
experimenting with the inclusion of URLs in LDAP and X.500 directories. This document builds on the
experimentation to date and defines a new attribute type and an auxiliary object class to allow URIs,
including URLs, to be stored in directory entries in a standard way.
Other LDAP Related RFCs - Best Current Practice
RFC-4521 Considerations for Lightweight Directory Access Protocol (LDAP) Extensions
http://www.ietf.org/rfc/rfc4521.txt
The Lightweight Directory Access Protocol (LDAP) is extensible. It provides mechanisms for adding new
operations, extending existing operations, and expanding user and system schemas. This document
discusses considerations for designers of LDAP extensions.
RFC-4520 Internet Assigned Numbers Authority (IANA) Considerations for the Lightweight Directory Access
Protocol (LDAP)
http://www.ietf.org/rfc/rfc4520.txt
This document provides procedures for registering extensible elements of the Lightweight Directory Access
Protocol (LDAP). The document also provides guidelines to the Internet Assigned Numbers Authority (IANA)
describing conditions under which new values can be assigned.
RFC-2148 Deployment of the Internet White Pages Service
http://www.ietf.org/rfc/rfc2148.txt
The Internet is used for information exchange and communication between its users. It can only be
effective as such if users are able to find each other's addresses. Therefore the Internet benefits from
an adequate White Pages Service, i.e., a directory service offering (Internet) address information
related to people and organizations.
This document describes the way in which the Internet White Pages Service (from now on abbreviated as
IWPS) is best exploited using today's experience, today's protocols, today's products and today's
procedures.
Other LDAP Related RFCs - Informational
RFC-5803 Lightweight Directory Access Protocol (LDAP) Schema for Storing Salted Challenge Response
Authentication Mechanism (SCRAM) Secrets
http://www.ietf.org/rfc/rfc5803.txt
This memo describes how the "authPassword" Lightweight Directory Access Protocol (LDAP) attribute can be
used for storing secrets used by the Salted Challenge Response Authentication Mechanism (SCRAM) mechanism
in the Simple Authentication and Security Layer (SASL) framework.
RFC-4876 A Configuration Profile Schema for Lightweight Directory Access Protocol (LDAP)-Based Agents
http://www.ietf.org/rfc/rfc4828.txt
This document consists of two primary components, a schema for agents that make use of the Lightweight
Directory Access protocol (LDAP) and a proposed use case of that schema, for distributed configuration of
similar directory user agents. A set of attribute types and an object class are proposed. In the
proposed use case, directory user agents (DUAs) can use this schema to determine directory data location
and access parameters for specific services they support. In addition, in the proposed use case,
attribute and object class mapping allows DUAs to reconfigure their expected (default) schema to match
that of the end user's environment. This document is intended to be a skeleton for future documents that
describe configuration of specific DUA services.
RFC-4529 Requesting Attributes by Object Class in the Lightweight Directory Access Protocol (LDAP)
http://www.ietf.org/rfc/rfc4529.txt
The Lightweight Directory Access Protocol (LDAP) search operation provides mechanisms for clients to
request all user application attributes, all operational attributes, and/or attributes selected by their
description. This document extends LDAP to support a mechanism that LDAP clients may use to request the
return of all attributes of an object class.
RFC-4525 Lightweight Directory Access Protocol (LDAP) Modify-Increment Extension
http://www.ietf.org/rfc/rfc4525.txt
This document describes an extension to the Lightweight Directory Access Protocol (LDAP) Modify operation
to support an increment capability. This extension is useful in provisioning applications, especially
when combined with the assertion control and/or the pre- read or post-read control extension.
RFC-4403 Lightweight Directory Access Protocol (LDAP) Schema for Universal Description, Discovery, and
Integration version 3 (UDDIv3)
http://www.ietf.org/rfc/rfc4403.txt
This document defines the Lightweight Directory Access Protocol (LDAPv3) schema for representing
Universal Description, Discovery, and Integration (UDDI) data types in an LDAP directory. It defines the
LDAP object class and attribute definitions and containment rules to model UDDI entities, defined in the
UDDI version 3 information model, in an LDAPv3-compliant directory.
RFC-4373 Lightweight Directory Access Protocol (LDAP) Bulk Update/Replication Protocol (LBURP)
http://www.ietf.org/rfc/rfc4373.txt
The Lightweight Directory Access Protocol (LDAP) Bulk Update/Replication Protocol (LBURP) allows an LDAP
client to perform a bulk update to an LDAP server. The protocol frames a sequenced set of update
operations within a pair of LDAP extended operations to notify the server that the update operations in
the framed set are related in such a way that the ordering of all operations can be preserved during
processing even when they are sent asynchronously by the client. Update operations can be grouped within
a single protocol message to maximize the efficiency of client-server communication.
The protocol is suitable for efficiently making a substantial set of updates to the entries in an LDAP
server.
RFC-3944 H.350 Directory Services
http://www.ietf.org/rfc/rfc3944.txt
The International Telecommunications Union Standardization Sector (ITU-T) has created the H.350 series of
Recommendations that specify directory services architectures in support of multimedia conferencing
protocols. The goal of the architecture is to 'directory enable' multimedia conferencing so that these
services can leverage existing identity management and enterprise directories. A particular goal is to
enable an enterprise or service provider to maintain a canonical source of users and their multimedia
conferencing systems, so that multiple call servers from multiple vendors, supporting multiple protocols,
can all access the same data store.
Because SIP is an IETF standard, the contents of H.350 and H.350.4 are made available via this document
to the IETF community. This document contains the entire normative text of ITU-T Recommendations H.350
and H.350.4 in sections 4 and 5, respectively. The remaining sections are included only in this
document, not in the ITU-T version.
RFC-3829 Lightweight Directory Access Protocol (LDAP) Authorization Identity Request and Response Controls
http://www.ietf.org/rfc/rfc3829.txt
This document extends the Lightweight Directory Access Protocol (LDAP) bind operation with a mechanism
for requesting and returning the authorization identity it establishes. Specifically, this document
defines the Authorization Identity Request and Response controls for use with the Bind operation.
RFC-3712 Lightweight Directory Access Protocol (LDAP): Schema for Printer Services
http://www.ietf.org/rfc/rfc3712.txt
This document defines a schema, object classes and attributes, for printers and printer services, for use
with directories that support Lightweight Directory Access Protocol v3 (LDAP-TS). This document is based
on the printer attributes listed in Appendix E of Internet Printing Protocol/1.1 (IPP) (RFC 2911). A few
additional printer attributes are based on definitions in the Printer MIB (RFC 1759).
RFC-3494 Lightweight Directory Access Protocol version 2 (LDAPv2) to Historic Status
http://www.ietf.org/rfc/rfc3494.txt
This document recommends the retirement of version 2 of the Lightweight Directory Access Protocol
(LDAPv2) and other dependent specifications, and discusses the reasons for doing so. This document
recommends RFC 1777, 1778, 1779, 1781, and 2559 (as well as documents they superseded) be moved to
Historic status.
RFC-3384 Lightweight Directory Access Protocol (version 3) Replication Requirements
http://www.ietf.org/rfc/rfc3384.txt
This document discusses the fundamental requirements for replication of data accessible via the
Lightweight Directory Access Protocol (version 3) (LDAPv3). It is intended to be a gathering place for
general replication requirements needed to provide interoperability between informational directories.
RFC-3112 LDAP Authentication Password Schema
http://www.ietf.org/rfc/rfc3112.txt
This document describes schema in support of user/password authentication in a LDAP (Lightweight
Directory Access Protocol) directory including the authPassword attribute type. This attribute type
holds values derived from the user's password(s) (commonly using cryptographic strength one-way hash).
authPassword is intended to used instead of userPassword.
RFC-3045 Storing Vendor Information in the LDAP root DSE
http://www.ietf.org/rfc/rfc3045.txt
This document specifies two Lightweight Directory Access Protocol (LDAP) attributes, vendorName and
vendorVersion that MAY be included in the root DSA-specific Entry (DSE) to advertise vendor-specific
information. These two attributes supplement the attributes defined in section 3.4 of RFC 2251.
RFC-2985 PKCS #9: Selected Object Classes and Attribute Types Version 2.0
http://www.ietf.org/rfc/rfc2985.txt
This memo provides a selection of object classes and attribute types for use in conjunction with public-
key cryptography and Lightweight Directory Access Protocol (LDAP) accessible directories. It also
includes ASN.1 syntax for all constructs.
RFC-2967 TISDAG - Technical Infrastructure for Swedish Directory Access Gateways
http://www.ietf.org/rfc/rfc2967.txt
The strength of the TISDAG (Technical Infrastructure for Swedish Directory Access Gateways) project's DAG
proposal is that it defines the necessary technical infrastructure to provide a single-access- point
service for information on Swedish Internet users. The resulting service will provide uniform access for
all information -- the same level of access to information (7x24 service), and the same information made
available, irrespective of the service provider responsible for maintaining that information, their
directory service protocols, or the end-user's client access protocol.
RFC-2927 MIME Directory Profile for LDAP Schema
http://www.ietf.org/rfc/rfc2927.txt
This document defines a multipurpose internet mail extensions (MIME) directory profile for holding a
lightweight directory access protocol (LDAP) schema. It is intended for communication with the Internet
schema listing service.
RFC-2926 Conversion of LDAP Schemas to and from SLP Templates
http://www.ietf.org/rfc/rfc2926.txt
This document describes a procedure for mapping between Service Location Protocol (SLP) service
advertisements and lightweight directory access protocol (LDAP) descriptions of services. The document
covers two aspects of the mapping. One aspect is mapping between SLP service type templates and LDAP
directory schema. Because the SLP service type template grammar is relatively simple, mapping from
service type templates to LDAP types is straightforward. Mapping in the other direction is
straightforward if the attributes are restricted to use just a few of the syntaxes defined in RFC 2252.
If arbitrary ASN.1 types occur in the schema, then the mapping is more complex and may even be
impossible. The second aspect is representation of service information in an LDAP directory. The
recommended representation simplifies interoperability with SLP by allowing SLP directory agents to
backend into LDAP directory servers. The resulting system allows service advertisements to propagate
easily between SLP and LDAP.
RFC-2820 Access Control Requirements for LDAP
http://www.ietf.org/rfc/rfc2820.txt
This document describes the fundamental requirements of an access control list (ACL) model for the LDAP
directory service. It is intended to be a gathering place for access control requirements needed to
provide authorized access to and interoperability between directories.
RFC-2798 Definition of the inetOrgPerson Object Class
http://www.ietf.org/rfc/rfc2798.txt
While the X.500 standards define many useful attribute types [X520] and object classes [X521], they do
not define a person object class that meets the requirements found in today's Internet and Intranet
directory service deployments. We define a new object class called inetOrgPerson for use in LDAP and
X.500 directory services that extends the X.521 standard organizationalPerson class to meet these needs.
RFC-2714 Schema for Representing CORBA Objects in an LDAP Directory
http://www.ietf.org/rfc/rfc2714.txt
CORBA is the Common Object Request Broker Architecture defined by the Object Management Group. This
document defines the schema for representing CORBA object references in an LDAP directory.
RFC-2713 Schema for Representing Java Objects in an LDAP Directory
http://www.ietf.org/rfc/rfc2713.txt
This document defines the schema for representing Java objects in an LDAP directory. It defines schema
elements to represent a Java serialized object, a Java marshalled object, a Java remote object, and a
JNDI reference.
RFC-2696 LDAP Control Extension for Simple Paged Results Manipulation
http://www.ietf.org/rfc/rfc2696.txt
This document describes an LDAPv3 control extension for simple paging of search results. This control
extension allows a client to control the rate at which an LDAP server returns the results of an LDAP
search operation. This control may be useful when the LDAP client has limited resources and may not be
able to process the entire result set from a given LDAP query, or when the LDAP client is connected over
a low-bandwidth connection. Other operations on the result set are not defined in this extension. This
extension is not designed to provide more sophisticated result set management.
RFC-1823 The LDAP Application Program Interface
http://www.ietf.org/rfc/rfc1823.txt
This document defines a C language application program interface to LDAP, which is designed to be
powerful, yet simple to use. It defines compatible synchronous and asynchronous interfaces to LDAP to
suit a wide variety of applications. This document gives a brief overview of the LDAP model, then an
overview of how the API is used by an application program to obtain LDAP information. The API calls are
described in detail, followed by an appendix that provides some example code demonstrating the use of the
API.
Other LDAP Related RFCs - Experimental
RFC-5805 Lightweight Directory Access Protocol (LDAP) Transactions
http://www.ietf.org/rfc/rfc5805.txt
Lightweight Directory Access Protocol (LDAP) update operations, such as Add, Delete, and Modify
operations, have atomic, consistency, isolation, durability (ACID) properties. Each of these update
operations act upon an entry. It is often desirable to update two or more entries in a single unit of
interaction, a transaction. Transactions are necessary to support a number of applications including
resource provisioning. This document extends LDAP to support transactions.
RFC-4533 The Lightweight Directory Access Protocol (LDAP) Content Synchronization Operation
http://www.ietf.org/rfc/rfc4533.txt
This specification describes the Lightweight Directory Access Protocol (LDAP) Content Synchronization
Operation. The operation allows a client to maintain a copy of a fragment of the Directory Information
Tree (DIT). It supports both polling for changes and listening for changes. The operation is defined as
an extension of the LDAP Search Operation.
RFC-4531 Lightweight Directory Access Protocol (LDAP) Turn Operation
http://www.ietf.org/rfc/rfc4531.txt
This specification describes a Lightweight Directory Access Protocol (LDAP) extended operation to reverse
(or "turn") the roles of client and server for subsequent protocol exchanges in the session, or to enable
each peer to act as both client and server with respect to the other.
RFC-3663 Domain Administrative Data in Lightweight Directory Access Protocol (LDAP)
http://www.ietf.org/rfc/rfc3663.txt
Domain registration data has typically been exposed to the general public via Nicname/Whois for
administrative purposes. This document describes the Referral Lightweight Directory Access Protocol
(LDAP) Service, an experimental service using LDAP and well-known LDAP types to make domain
administrative data available.
RFC-3088 OpenLDAP Root Service - An experimental LDAP referral service
http://www.ietf.org/rfc/rfc3088.txt
The OpenLDAP Project is operating an experimental LDAP (Lightweight Directory Access Protocol) referral
service known as the "OpenLDAP Root Service". The automated system generates referrals based upon
service location information published in DNS SRV RRs (Domain Name System location of services resource
records). This document describes this service.
RFC-2657 LDAPv2 Client vs. the Index Mesh
http://www.ietf.org/rfc/rfc2657.txt
LDAPv2 clients as implemented according to RFC 1777 have no notion of referral. The integration between
such a client and an Index Mesh, as defined by the Common Indexing Protocol, heavily depends on referrals
and therefore needs to be handled in a special way. This document defines one possible way of doing this.
RFC-2649 Signed Directory Operations Using S/MIME
http://www.ietf.org/rfc/rfc2649.txt
This document defines an LDAPv3 based mechanism for signing directory operations in order to create a
secure journal of changes that have been made to each directory entry. Both client and server based
signatures are supported. An object class for subsequent retrieval are 'journal entries' is also defined.
This document specifies LDAPv3 controls that enable this functionality. It also defines an LDAPv3 schema
that allows for subsequent browsing of the journal information.
RFC-2307 An Approach for Using LDAP as a Network Information Service
http://www.ietf.org/rfc/rfc2307.txt
This document describes an experimental mechanism for mapping entities related to TCP/IP and the UNIX
system into X.500 entries so that they may be resolved with the LDAP. A set of attribute types and object
classes are proposed, along with specific guidelines for interpreting them. The intention is to assist
the deployment of LDAP as an organizational nameservice. No proposed solutions are intended as standards
for the Internet. Rather, it is hoped that a general consensus will emerge as to the appropriate solution
to such problems, leading eventually to the adoption of standards. The proposed mechanism has already
been implemented with some success.
Expired but still interesting Internet Drafts
draft-wahl-ldap-adminaddr -- Administrator Address Attribute
Organizations running multiple directory servers need an ability for administrators to determine who is
responsible for a particular server. This is conceptually similar to the 'sysContact' object of SNMP. The
administratorsAddress attribute allows a server administrator to provide the contact information of the
responsible party for an LDAP server. This can be used by management clients which are, for example,
checking the state of a replication or referral topology, to provide a way for the user of the management
client to send email to manager of a particular server.
draft-zeilenga-ldap-noop -- The LDAP No-Op Control
This document defines the Lightweight Directory Access Protocol (LDAP) No-Op control which can be used to
disable the normal effect of an operation. The control can be used to discover how a server might react
to a particular update request without updating the directory.
draft-legg-ldap-transfer -- Lightweight Directory Access Protocol (LDAP): Transfer Encoding Options
Each attribute stored in a Lightweight Directory Access Protocol (LDAP) directory has a defined syntax
(i.e., data type). A syntax definition specifies how attribute values conforming to the syntax are
normally represented when transferred in LDAP operations. This representation is referred to as the
LDAP-specific encoding to distinguish it from other methods of encoding attribute values. This document
introduces a new category of attribute options, called transfer encoding options, that can be used to
specify that the associated attribute values are encoded according to one of these other methods.
draft-furuseth-ldap-untypedobject -- Structural object class 'namedObject' for LDAP/X.500
This document defines an 'namedObject' structural object class for the Lightweight Directory Access
Protocol (LDAP) and X.500. This is useful for entries with no natural choice of structural object class,
e.g. if an entry must exist even though its contents are uninteresting.
draft-wahl-ldap-p3p -- P3P Policy Attributes for LDAP
This document defines attributes that can be retrieved via Lightweight Directory Access Protocol version
3 (LDAP) requests, which contain URIs pointing to the privacy policy documents. These documents describe
the privacy policy concerning access to a directory server, and the privacy policies that apply to the
contents of the directory (a subtree of entries).
draft-chu-ldap-xordered -- Ordered Entries and Values in LDAP
As LDAP is used more extensively for managing various kinds of data, one often encounters a need to
preserve both the ordering and the content of data, despite the inherently unordered structure of entries
and attribute values in the directory. This document describes a scheme to attach ordering information
to attributes in a directory so that the ordering may be preserved and propagated to other LDAP
applications.
draft-chu-ldap-logschema -- A Schema for Logging the LDAP Protocol
In order to facilitate remote administration and auditing of LDAP server operation, it is desirable to
provide the server's operational logs themselves as a searchable LDAP directory. These logs may also be
used as a persistent change log to support various replication mechanisms. This document defines a
schema that may be used to represent all of the requests that have been processed by an LDAP server. It
may be used by various applications for auditing, flight recorder, replication, and other purposes.
draft-zeilenga-ldap-relax -- The LDAP Relax Rules Control
This document defines the Lightweight Directory Access Protocol (LDAP) Relax Rules Control which allows a
directory user agent (a client) to request the directory service temporarily relax enforcement of various
data and service model rules.
draft-gpaterno-dhcp-ldap -- DHCP Option for LDAP Directory Services discovery
This document defines a new DHCP option for delivering configuration information for LDAP services.
Through this option, the client receives an LDAP URL [8] of the closest available LDAP server/replica
that can be used to authenticate users or look up any useful data.
draft-schleiff-ldap-xri -- LDAP Schema for eXtensible Resource Identifier (XRI)
This document describes Attribute Types and an Object Class for use in representing XRI (eXtensible
Resource Identifier) values in LDAP (Lightweight Directory Access Protocol) and X.500 directory services.
draft-wahl-ldap-session -- LDAP Session Tracking Control
Many network devices, application servers, and middleware components of a enterprise software
infrastructure generate some form of session tracking identifiers, which are useful when analyzing
activity and accounting logs to group activity relating to a particular session. This document discusses
how Lightweight Directory Access Protocol version 3 (LDAP) clients can include session tracking
identifiers with their LDAP requests. This information is provided through controls in the requests the
clients send to LDAP servers. The LDAP server receiving these controls can include the session tracking
identifiers the log messages it writes, enabling LDAP requests in the LDAP server's logs to be correlated
with activity in logs of other components in the infrastructure. The control also enables session
tracking information to be generated by LDAP servers and returned to clients and other servers. Three
formats of session tracking identifiers are defined in this document.
draft-wahl-ldap-subtree-source -- LDAP Subtree Data Source URI Attribute
This document defines an attribute that enables administrative clients using the Lightweight Directory
Access Protocol (LDAP) to determine the source of directory entries.
draft-ietf-ldapext-psearch -- Persistent Search: A Simple LDAP Change Notification Mechanism
This document defines two controls that extend the LDAPv3 search operation to provide a simple mechanism
by which an LDAP client can receive notification of changes that occur in an LDAP server. The mechanism
is designed to be very flexible yet easy for clients and servers to implement.
draft-ietf-ldapext-ldapv3-vlv -- LDAP Extensions for Scrolling View Browsing of Search Results
This document describes a Virtual List View control extension for the LDAP Search operation. This
control is designed to allow the "virtual list box" feature, common in existing commercial e-mail
address book applications, to be supported efficiently by LDAP servers. LDAP servers' inability to
support this client feature is a significant impediment to LDAP replacing proprietary protocols in
commercial e-mail systems.
The control allows a client to specify that the server return, for a given LDAP search with
associated sort keys, a contiguous subset of the search result set. This subset is specified in terms of
offsets into the ordered list, or in terms of a greater than or equal comparison value.
