NAME

       kopano-ldap.cfg - The Kopano LDAP configuration file

SYNOPSIS

       ldap.cfg

DESCRIPTION

       The ldap.cfg is a configuration file for LDAP user plugin. All options to correctly
       retrieve user and group information can be set here.

FILE FORMAT

       The file consists of one big section, but parameters can be grouped by functionality.

       The parameters are written in the form:

       name = value

       The file is line-based. Each newline-terminated line represents either a comment, nothing,
       a parameter or a directive. A line beginning with `#' is considered a comment, and will be
       ignored by Kopano. Parameter names are case sensitive. Lines beginning with `!' are
       directives.

       Directives are written in the form:

       !directive [argument(s)]

       The following directives exist:

       include
           Include and process argument

           Example: !include common.cfg

       propmap
           Propmap delivers the capabilities to map additional attributes to addressbook
           properties (e.g. firstname, lastname, telephonenumber).

           In the propmap the configuration names must be the hex property tag of the requested
           property. The value given to the configuration name must be the LDAP attribute to
           which the property should be mapped.

           Example: !propmap ldap.propmap.cfg

EXPLANATION OF EACH PARAMETER

   ldap_host, ldap_port, ldap_protocol
       These historic directives specify a single LDAP server to use. Its use is discouraged in
       favor of ldap_uri.

       Defaults: ldap_host=localhost, ldap_port=389, ldap_protocol=ldap

   ldap_uri
       Specifies the URI of one or more LDAP server(s) to use, without any DN portion, such as
       "ldap://server:389/", "ldaps://server:636/" or "ldapi:///". If ldap_uri is set, the values
       of the historic directives ldap_host, ldap_port and ldap_protocol are ignored.

       Default: (empty, such that URI list is constructed from ldap_host, ldap_port,
       ldap_protocol)

   ldap_starttls
       Request that any LDAP connections be secured with TLS, and reject the connection if this
       security cannot be established. See the OpenLDAP documentation for setting up ldap.cfg and
       TLS requirements.

       Default: no

   ldap_server_charset
       The charset that the LDAP server uses to store strings. All strings sent to the LDAP
       server or retrieved from the server will be interpreted in this charset. In most setups,
       utf-8 is used, but may also be iso-8859-15. All charsets supported by the system iconv()
       are supported here.

       Default: utf-8

   ldap_bind_user
       The bind dn as to connect to the LDAP server. Leave empty to connect anonymous.

       Default value is empty.

   ldap_bind_passwd
       When ldap_bind_user is a valid DN, this should be filled in too.

       Default value is empty.

   ldap_network_timeout
       The timeout for network operations in seconds.

       Default: 30

   ldap_last_modification_attribute
       This value is used to detect changes in the item in the LDAP server. Since it is a
       standard LDAP attribute, you should never have to change this. It is mainly used for
       addressbook synchronisation between your server and your offline data.

       Default: modifyTimeStamp

   ldap_page_size
       Limit result sets in pages of this size, downloading fewer results at a time from the LDAP
       server.

       Default: 1000

   ldap_search_base
       This is the subtree entry where all objects are defined in the LDAP server.

       Default: dc=kopano,dc=com

   ldap_object_type_attribute
       An object is defined by this attribute what type it is, e.g. user, group, etc. Every
       object type should have a unique value in this attribute in order to define what which
       entry is.

       The value of this attribute must be specified in the ldap_*_type_attribute_value settings.
       Each of those settings may specify multiple values for the type attribute, separated by
       comma's. All of these values must be present in the objects type attribute for a match to
       be made and the object to be recognised as that type.

       It is possible for ambiguities to arise by setting the same string for multiple
       ldap_*_type_attribute_value settings. This ambiguity will be resolved by preferring
       objects with more matching values. If the ambiguity cannot be resolved in this way, then
       the first possibility is chosen from the list (addresslist, tenant, dynamic group, group,
       contact, user).

       Default: objectClass

   ldap_user_type_attribute_value

       This value indicates if a user is nonactive. Nonactive users cannot login, but the store
       can be used as a shared store for other users.

       Setting this value to 1 will make a mailbox nonactive. The nonactive attribute provided by
       the Kopano schema for nonactive users is kopanoSharedStoreOnly

       Default: kopanoSharedStoreOnly

   ldap_resource_type_attribute
       This attribute can change the type of a non-active user. The value of this attribute can

       Default for ADS: distinguishedName

   ldap_user_certificate_attribute
       The attribute which contains the user's public certificate to be used for encrypted S/MIME
       messages. Both Active Directory and OpenLDAP use the same ldap attribute by default. The
       format of the certificate should be the binary DER format.

       Default: userCertificate

   ldap_group_search_filter
       Adds an extra filter to the group search.

       Default: Empty, using ldap_user_unique_attribute

   ldap_quota_companywarning_recipients_attribute
       This attribute contains the list of users who will receive an email when a tenant exceeds
       its quota. The system administrator of the tenant that is over quota will automatically be

       The attribute of the user which is listed in
       ldap_quota_companywarning_recipients_attribute

       Default: Empty, using ldap_user_unique_attribute

   ldap_addressbook_hide_attribute
       The attribute indicating the object must be hidden from the addressbook. The object will
       still be detected as kopano user and is allowed to login and work as regular kopano user,
       but will not be visible in the addressbook for other users.

       Default: kopanoHidden

   ldap_object_search_filter
       When searching in the addressbook, this filter will be used. Normally, the storage server
       will only search in the unique attribute, loginname, fullname and emailaddress. You might
       want to search in more fields, like 'lastname'. Kopano also uses a postfix wildcard only.
       Using the '*' wildcard with prefixes makes a search slower, but can return more results.

       Hint: Use the kopanoAccount attribute in the filter to differentiate between non-kopano
       and kopano objects.

       You can set a custom search filter here. '%s' will be replaced with the string being
       searched.

       Active Directory has a shortcut for searching in the addressbook using the 'anr'
       attribute. This is recommended on ADS installations.

       Default:

       Recommended for ADS installations: (anr=%s)

       Optional for OpenLDAP installations: (|(mail=%s*)(uid=%s*)(cn=*%s*)
       (fullname=*%s*)(givenname=*%s*)(lastname=*%s*)(sn=*%s*))

   ldap_filter_cutoff_elements
       When the ldap plugin retrieves information from the LDAP Server, large queries can be
       created to retrieve data for multiple objects at once. These large queries can perform
       badly on some LDAP server implementations. This option limits the number of elements that
       can be retrieved in one search filter and therefore limits the size of the filter.
       Instead, a broader search filter is created which retrieves all objects from the LDAP
       server. This results in slightly higher processing overhead and network activity, but with
       the bonus that the query can be served by the LDAP server much faster (a factor of 40 in
       5000-object queries has been observed).

       Setting this value to 0 will never limit the filter, setting it to a value of 1 will
       always limit the filter (since all queries will be retrieving one or more objects).

       Default: 1000
