NAME

       sudoers.ldap - sudo LDAP configuration

DESCRIPTION

       In addition to the standard sudoers file, sudo may be configured via LDAP.  This can be
       especially useful for synchronizing sudoers in a large, distributed environment.

       Using LDAP for sudoers has several benefits:

       ·   sudo no longer needs to read sudoers in its entirety.  When LDAP is used, there are
           only two or three LDAP queries per invocation.  This makes it especially fast and
           particularly usable in LDAP environments.

       ·   sudo no longer exits if there is a typo in sudoers.  It is not possible to load LDAP
           data into the server that does not conform to the sudoers schema, so proper syntax is
           guaranteed.  It is still possible to have typos in a user or host name, but this will
           not prevent sudo from running.

       ·   It is possible to specify per-entry options that override the global default options.
           /etc/sudoers only supports default options and limited options associated with
           user/host/commands/aliases.  The syntax is complicated and can be difficult for users
           to understand.  Placing the options directly in the entry is more natural.

       ·   The visudo program is no longer needed.  visudo provides locking and syntax checking
           of the /etc/sudoers file.  Since LDAP updates are atomic, locking is no longer
           necessary.  Because syntax is checked when the data is inserted into LDAP, there is no
           need for a specialized tool to check syntax.

       Another major difference between LDAP and file-based sudoers is that in LDAP,
       sudo-specific Aliases are not supported.

       For the most part, there is really no need for sudo-specific Aliases.  Unix groups or user
       netgroups can be used in place of User_Aliases and Runas_Aliases.  Host netgroups can be
       used in place of Host_Aliases.  Since Unix groups and netgroups can also be stored in LDAP
       there is no real need for sudo-specific aliases.

       Cmnd_Aliases are not really required either since it is possible to have multiple users
       listed in a sudoRole.  Instead of defining a Cmnd_Alias that is referenced by multiple
       users, one can create a sudoRole that contains the commands and assign multiple users to
       it.

   SUDOers LDAP container
       The sudoers configuration is contained in the ou=SUDOers LDAP container.

       Sudo first looks for the cn=default entry in the SUDOers container.  If found, the multi-
       valued sudoOption attribute is parsed in the same manner as a global Defaults line in
       /etc/sudoers.  In the following example, the SSH_AUTH_SOCK variable will be preserved in
       the environment for all users.

           dn: cn=defaults,ou=SUDOers,dc=example,dc=com
           objectClass: top
           objectClass: sudoRole
           cn: defaults
           description: Default sudoOption's go here
           sudoOption: env_keep+=SSH_AUTH_SOCK

       The equivalent of a sudoer in LDAP is a sudoRole.  It consists of the following
       attributes:

       sudoUser
           A user name, uid (prefixed with '#'), Unix group (prefixed with a '%') or user
           netgroup (prefixed with a '+').

       sudoHost
           A host name, IP address, IP network, or host netgroup (prefixed with a '+').  The
           special value ALL will match any host.

       sudoCommand
           A Unix command with optional command line arguments, potentially including globbing
           characters (aka wild cards).  The special value ALL will match any command.  If a
           command is prefixed with an exclamation point '!', the user will be prohibited from
           running that command.

       sudoOption
           Identical in function to the global options described above, but specific to the
           sudoRole in which it resides.

       sudoRunAsUser
           A user name or uid (prefixed with '#') that commands may be run as or a Unix group
           (prefixed with a '%') or user netgroup (prefixed with a '+') that contains a list of
           users that commands may be run as.  The special value ALL will match any user.

           The sudoRunAsUser attribute is only available in sudo versions 1.7.0 and higher.
           Older versions of sudo use the sudoRunAs attribute instead.

       sudoRunAsGroup
           A Unix group or gid (prefixed with '#') that commands may be run as.  The special
           value ALL will match any group.

           The sudoRunAsGroup attribute is only available in sudo versions 1.7.0 and higher.

       sudoNotBefore
           A timestamp in the form yyyymmddHHMMSSZ that can be used to provide a start date/time
           for when the sudoRole will be valid.  If multiple sudoNotBefore entries are present,
           the earliest is used.  Note that timestamps must be in Coordinated Universal Time
           (UTC), not the local timezone.  The minute and seconds portions are optional, but some
           LDAP servers require that they be present (contrary to the RFC).

           The sudoNotBefore attribute is only available in sudo versions 1.7.5 and higher and
           must be explicitly enabled via the SUDOERS_TIMED option in /etc/sudo-ldap.conf.

       sudoNotAfter
           A timestamp in the form yyyymmddHHMMSSZ that indicates an expiration date/time, after
           which the sudoRole will no longer be valid.  If multiple sudoNotBefore entries are
           present, the last one is used.  Note that timestamps must be in Coordinated Universal
           Time (UTC), not the local timezone.  The minute and seconds portions are optional, but
           some LDAP servers require that they be present (contrary to the RFC).

           The sudoNotAfter attribute is only available in sudo versions 1.7.5 and higher and
           must be explicitly enabled via the SUDOERS_TIMED option in /etc/sudo-ldap.conf.

       sudoOrder
           The sudoRole entries retrieved from the LDAP directory have no inherent order.  The
           sudoOrder attribute is an integer (or floating point value for LDAP servers that
           support it) that is used to sort the matching entries.  This allows LDAP-based sudoers
           entries to more closely mimic the behaviour of the sudoers file, where the of the
           entries influences the result.  If multiple entries match, the entry with the highest
           sudoOrder attribute is chosen.  This corresponds to the "last match" behavior of the
           sudoers file.  If the sudoOrder attribute is not present, a value of 0 is assumed.

           The sudoOrder attribute is only available in sudo versions 1.7.5 and higher.

       Each attribute listed above should contain a single value, but there may be multiple
       instances of each attribute type.  A sudoRole must contain at least one sudoUser, sudoHost
       and sudoCommand.

       The following example allows users in group wheel to run any command on any host via sudo:

           dn: cn=%wheel,ou=SUDOers,dc=example,dc=com
           objectClass: top
           objectClass: sudoRole
           cn: %wheel
           sudoUser: %wheel
           sudoHost: ALL
           sudoCommand: ALL

   Anatomy of LDAP sudoers lookup
       When looking up a sudoer using LDAP there are only two or three LDAP queries per
       invocation.  The first query is to parse the global options.  The second is to match
       against the user's name and the groups that the user belongs to.  (The special ALL tag is
       matched in this query too.)  If no match is returned for the user's name and groups, a
       third query returns all entries containing user netgroups and checks to see if the user
       belongs to any of them.

       If timed entries are enabled with the SUDOERS_TIMED configuration directive, the LDAP
       queries include a subfilter that limits retrieval to entries that satisfy the time
       constraints, if any.

   Differences between LDAP and non-LDAP sudoers
       There are some subtle differences in the way sudoers is handled once in LDAP.  Probably
       the biggest is that according to the RFC, LDAP ordering is arbitrary and you cannot expect
       that Attributes and Entries are returned in any specific order.

       The order in which different entries are applied can be controlled using the sudoOrder
       attribute, but there is no way to guarantee the order of attributes within a specific
       entry.  If there are conflicting command rules in an entry, the negative takes precedence.
       This is called paranoid behavior (not necessarily the most specific match).

       Here is an example:

           # /etc/sudoers:
           # Allow all commands except shell
           johnny  ALL=(root) ALL,!/bin/sh
           # Always allows all commands because ALL is matched last
           puddles ALL=(root) !/bin/sh,ALL

           # LDAP equivalent of johnny
           # Allows all commands except shell
           dn: cn=role1,ou=Sudoers,dc=my-domain,dc=com
           objectClass: sudoRole
           objectClass: top
           cn: role1
           sudoUser: johnny
           sudoHost: ALL
           sudoCommand: ALL
           sudoCommand: !/bin/sh

           # LDAP equivalent of puddles
           # Notice that even though ALL comes last, it still behaves like
           # role1 since the LDAP code assumes the more paranoid configuration
           dn: cn=role2,ou=Sudoers,dc=my-domain,dc=com
           objectClass: sudoRole
           objectClass: top
           cn: role2
           sudoUser: puddles
           sudoHost: ALL
           sudoCommand: !/bin/sh
           sudoCommand: ALL

       Another difference is that negations on the Host, User or Runas are currently ignored.
       For example, the following attributes do not behave the way one might expect.

           # does not match all but joe
           # rather, does not match anyone
           sudoUser: !joe

           # does not match all but joe
           # rather, matches everyone including Joe
           sudoUser: ALL
           sudoUser: !joe

           # does not match all but web01
           # rather, matches all hosts including web01
           sudoHost: ALL
           sudoHost: !web01

   Sudoers Schema
       In order to use sudo's LDAP support, the sudo schema must be installed on your LDAP
       server.  In addition, be sure to index the 'sudoUser' attribute.

       Three versions of the schema: one for OpenLDAP servers (schema.OpenLDAP), one for
       Netscape-derived servers (schema.iPlanet), and one for Microsoft Active Directory
       (schema.ActiveDirectory) may be found in the sudo distribution.

       The schema for sudo in OpenLDAP form is included in the EXAMPLES section.

   Configuring ldap.conf
       Sudo reads the /etc/sudo-ldap.conf file for LDAP-specific configuration.  Typically, this
       file is shared amongst different LDAP-aware clients.  As such, most of the settings are
       not sudo-specific.  Note that sudo parses /etc/sudo-ldap.conf itself and may support
       options that differ from those described in the ldap.conf(5) manual.

       Also note that on systems using the OpenLDAP libraries, default values specified in
       /etc/openldap/ldap.conf or the user's .ldaprc files are not used.

       Only those options explicitly listed in /etc/sudo-ldap.conf as being supported by sudo are
       honored.  Configuration options are listed below in upper case but are parsed in a case-
       independent manner.

       URI ldap[s]://[hostname[:port]] ...
           Specifies a whitespace-delimited list of one or more URIs describing the LDAP
           server(s) to connect to.  The protocol may be either ldap or ldaps, the latter being
           for servers that support TLS (SSL) encryption.  If no port is specified, the default
           is port 389 for ldap:// or port 636 for ldaps://.  If no hostname is specified, sudo
           will connect to localhost.  Multiple URI lines are treated identically to a URI line
           containing multiple entries.  Only systems using the OpenSSL libraries support the
           mixing of ldap:// and ldaps:// URIs.  The Netscape-derived libraries used on most
           commercial versions of Unix are only capable of supporting one or the other.

       HOST name[:port] ...
           If no URI is specified, the HOST parameter specifies a whitespace-delimited list of
           LDAP servers to connect to.  Each host may include an optional port separated by a
           colon (':').  The HOST parameter is deprecated in favor of the URI specification and
           is included for backwards compatibility.

       PORT port_number
           If no URI is specified, the PORT parameter specifies the default port to connect to on
           the LDAP server if a HOST parameter does not specify the port itself.  If no PORT
           parameter is used, the default is port 389 for LDAP and port 636 for LDAP over TLS
           (SSL).  The PORT parameter is deprecated in favor of the URI specification and is
           included for backwards compatibility.

       BIND_TIMELIMIT seconds
           The BIND_TIMELIMIT parameter specifies the amount of time, in seconds, to wait while
           trying to connect to an LDAP server.  If multiple URIs or HOSTs are specified, this is
           the amount of time to wait before trying the next one in the list.

       NETWORK_TIMEOUT seconds
           An alias for BIND_TIMELIMIT for OpenLDAP compatibility.

       TIMELIMIT seconds
           The TIMELIMIT parameter specifies the amount of time, in seconds, to wait for a
           response to an LDAP query.

       TIMEOUT seconds
           The TIMEOUT parameter specifies the amount of time, in seconds, to wait for a response
           from the various LDAP APIs.

       SUDOERS_BASE base
           The base DN to use when performing sudo LDAP queries.  Typically this is of the form
           ou=SUDOers,dc=example,dc=com for the domain example.com.  Multiple SUDOERS_BASE lines
           may be specified, in which case they are queried in the order specified.

       SUDOERS_SEARCH_FILTER ldap_filter
           An LDAP filter which is used to restrict the set of records returned when performing a
           sudo LDAP query.  Typically, this is of the form attribute=value or
           (&(attribute=value)(attribute2=value2)).

       SUDOERS_TIMED on/true/yes/off/false/no
           Whether or not to evaluate the sudoNotBefore and sudoNotAfter attributes that
           implement time-dependent sudoers entries.

       SUDOERS_DEBUG debug_level
           This sets the debug level for sudo LDAP queries.  Debugging information is printed to
           the standard error.  A value of 1 results in a moderate amount of debugging
           information.  A value of 2 shows the results of the matches themselves.  This
           parameter should not be set in a production environment as the extra information is
           likely to confuse users.

       BINDDN DN
           The BINDDN parameter specifies the identity, in the form of a Distinguished Name (DN),
           to use when performing LDAP operations.  If not specified, LDAP operations are
           performed with an anonymous identity.  By default, most LDAP servers will allow
           anonymous access.

       BINDPW secret
           The BINDPW parameter specifies the password to use when performing LDAP operations.
           This is typically used in conjunction with the BINDDN parameter.

       ROOTBINDDN DN
           The ROOTBINDDN parameter specifies the identity, in the form of a Distinguished Name
           (DN), to use when performing privileged LDAP operations, such as sudoers queries.  The
           password corresponding to the identity should be stored in /etc/ldap.secret.  If not
           specified, the BINDDN identity is used (if any).

       LDAP_VERSION number
           The version of the LDAP protocol to use when connecting to the server.  The default
           value is protocol version 3.

       SSL on/true/yes/off/false/no
           If the SSL parameter is set to on, true or yes, TLS (SSL) encryption is always used
           when communicating with the LDAP server.  Typically, this involves connecting to the
           server on port 636 (ldaps).

       SSL start_tls
           If the SSL parameter is set to start_tls, the LDAP server connection is initiated
           normally and TLS encryption is begun before the bind credentials are sent.  This has
           the advantage of not requiring a dedicated port for encrypted communications.  This
           parameter is only supported by LDAP servers that honor the start_tls extension, such
           as the OpenLDAP server.

       TLS_CHECKPEER on/true/yes/off/false/no
           If enabled, TLS_CHECKPEER will cause the LDAP server's TLS certificated to be
           verified.  If the server's TLS certificate cannot be verified (usually because it is
           signed by an unknown certificate authority), sudo will be unable to connect to it.  If
           TLS_CHECKPEER is disabled, no check is made.  Note that disabling the check creates an
           opportunity for man-in-the-middle attacks since the server's identity will not be
           authenticated.  If possible, the CA's certificate should be installed locally so it
           can be verified.

       TLS_CACERT file name
           An alias for TLS_CACERTFILE for OpenLDAP compatibility.

       TLS_CACERTFILE file name
           The path to a certificate authority bundle which contains the certificates for all the
           Certificate Authorities the client knows to be valid, e.g. /etc/ssl/ca-bundle.pem.
           This option is only supported by the OpenLDAP libraries.  Netscape-derived LDAP
           libraries use the same certificate database for CA and client certificates (see
           TLS_CERT).

       TLS_CACERTDIR directory
           Similar to TLS_CACERTFILE but instead of a file, it is a directory containing
           individual Certificate Authority certificates, e.g. /etc/ssl/certs.  The directory
           specified by TLS_CACERTDIR is checked after TLS_CACERTFILE.  This option is only
           supported by the OpenLDAP libraries.

       TLS_CERT file name
           The path to a file containing the client certificate which can be used to authenticate
           the client to the LDAP server.  The certificate type depends on the LDAP libraries
           used.

           OpenLDAP:
               tls_cert /etc/ssl/client_cert.pem

           Netscape-derived:
               tls_cert /var/ldap/cert7.db

           When using Netscape-derived libraries, this file may also contain Certificate
           Authority certificates.

       TLS_KEY file name
           The path to a file containing the private key which matches the certificate specified
           by TLS_CERT.  The private key must not be password-protected.  The key type depends on
           the LDAP libraries used.

           OpenLDAP:
               tls_key /etc/ssl/client_key.pem

           Netscape-derived:
               tls_key /var/ldap/key3.db

       TLS_RANDFILE file name
           The TLS_RANDFILE parameter specifies the path to an entropy source for systems that
           lack a random device.  It is generally used in conjunction with prngd or egd.  This
           option is only supported by the OpenLDAP libraries.

       TLS_CIPHERS cipher list
           The TLS_CIPHERS parameter allows the administer to restrict which encryption
           algorithms may be used for TLS (SSL) connections.  See the OpenSSL manual for a list
           of valid ciphers.  This option is only supported by the OpenLDAP libraries.

       USE_SASL on/true/yes/off/false/no
           Enable USE_SASL for LDAP servers that support SASL authentication.

       SASL_AUTH_ID identity
           The SASL user name to use when connecting to the LDAP server.  By default, sudo will
           use an anonymous connection.

       ROOTUSE_SASL on/true/yes/off/false/no
           Enable ROOTUSE_SASL to enable SASL authentication when connecting to an LDAP server
           from a privileged process, such as sudo.

       ROOTSASL_AUTH_ID identity
           The SASL user name to use when ROOTUSE_SASL is enabled.

       SASL_SECPROPS none/properties
           SASL security properties or none for no properties.  See the SASL programmer's manual
           for details.

       KRB5_CCNAME file name
           The path to the Kerberos 5 credential cache to use when authenticating with the remote
           server.

       DEREF never/searching/finding/always
           How alias dereferencing is to be performed when searching.  See the ldap.conf(5)
           manual for a full description of this option.

       See the ldap.conf entry in the EXAMPLES section.

   Configuring nsswitch.conf
       Unless it is disabled at build time, sudo consults the Name Service Switch file,
       /etc/nsswitch.conf, to specify the sudoers search order.  Sudo looks for a line beginning
       with sudoers: and uses this to determine the search order.  Note that sudo does not stop
       searching after the first match and later matches take precedence over earlier ones.

       The following sources are recognized:

           files       read sudoers from F</etc/sudoers>
           ldap        read sudoers from LDAP

       In addition, the entry [NOTFOUND=return] will short-circuit the search if the user was not
       found in the preceding source.

       To consult LDAP first followed by the local sudoers file (if it exists), use:

           sudoers: ldap files

       The local sudoers file can be ignored completely by using:

           sudoers: ldap

       If the /etc/nsswitch.conf file is not present or there is no sudoers line, the following
       default is assumed:

           sudoers: files

       Note that /etc/nsswitch.conf is supported even when the underlying operating system does
       not use an nsswitch.conf file.

   Configuring netsvc.conf
       On AIX systems, the /etc/netsvc.conf file is consulted instead of /etc/nsswitch.conf.
       sudo simply treats netsvc.conf as a variant of nsswitch.conf; information in the previous
       section unrelated to the file format itself still applies.

       To consult LDAP first followed by the local sudoers file (if it exists), use:

           sudoers = ldap, files

       The local sudoers file can be ignored completely by using:

           sudoers = ldap

       To treat LDAP as authoratative and only use the local sudoers file if the user is not
       present in LDAP, use:

           sudoers = ldap = auth, files

       Note that in the above example, the auth qualfier only affects user lookups; both LDAP and
       sudoers will be queried for Defaults entries.

       If the /etc/netsvc.conf file is not present or there is no sudoers line, the following
       default is assumed:

           sudoers = files

FILES

       /etc/sudo-ldap.conf     LDAP configuration file

       /etc/nsswitch.conf      determines sudoers source order

       /etc/netsvc.conf        determines sudoers source order on AIX

         # Sudo can provide a client certificate when communicating to
         # the LDAP server.
         # Tips:
         #   * Enable both lines at the same time.
         #   * Do not password protect the key file.
         #   * Ensure the keyfile is only readable by root.
         #
         # For OpenLDAP:
         #tls_cert /etc/certs/client_cert.pem
         #tls_key  /etc/certs/client_key.pem
         #
         # For SunONE or iPlanet LDAP, tls_cert and tls_key may specify either
         # a directory, in which case the files in the directory must have the
         # default names (e.g. cert8.db and key4.db), or the path to the cert
         # and key files themselves.  However, a bug in version 5.0 of the LDAP
         # SDK will prevent specific file names from working.  For this reason
         # it is suggested that tls_cert and tls_key be set to a directory,
         # not a file name.
         #
         # The certificate database specified by tls_cert may contain CA certs
         # and/or the client's cert.  If the client's cert is included, tls_key
         # should be specified as well.
         # For backward compatibility, "sslpath" may be used in place of tls_cert.
         #tls_cert /var/ldap
         #tls_key /var/ldap
         #
         # If using SASL authentication for LDAP (OpenSSL)
         # use_sasl yes
         # sasl_auth_id <SASL user name>
         # rootuse_sasl yes
         # rootsasl_auth_id <SASL user name for root access>
         # sasl_secprops none

   Sudo schema for OpenLDAP
       The following schema, in OpenLDAP format, is included with sudo source and binary
       distributions as schema.OpenLDAP.  Simply copy it to the schema directory (e.g.
       /etc/openldap/schema), add the proper include line in slapd.conf and restart slapd.

CAVEATS

       Note that there are differences in the way that LDAP-based sudoers is parsed compared to
       file-based sudoers.  See the "Differences between LDAP and non-LDAP sudoers" section for
       more information.
