IDMAP_LDAP(8)


NAME

  idmap_ldap - Samba's idmap_ldap Backend for Winbind


DESCRIPTION

  The idmap_ldap plugin provides a means for Winbind to store and retrieve
  SID/uid/gid mapping tables in an LDAP directory service. The module
  implements both the "idmap" and "idmap alloc" APIs.


IDMAP OPTIONS

  ldap_base_dn = DN
     Defines the directory base suffix to use when searching for SID/uid/gid
     mapping entries. If not defined, idmap_ldap will default to using the
     "ldap idmap suffix" option from smb.conf.

  ldap_user_dn = DN
     Defines the user DN to be used for authentication. If absent an
     anonymous bind will be performed.

  ldap_url = ldap://server/
     Specifies the LDAP server to use when searching for existing SID/uid/gid
     map entries. If not defined, idmap_ldap will assume that
     ldap://localhost/ should be used.

  range = low - high
     Defines the available matching uid and gid range for which the backend
     is authoritative. Note that the range commonly matches the allocation
     range due to the fact that the same backend will store and retrieve
     SID/uid/gid mapping entries. If the parameter is absent, Winbind fail
     over to use the "idmap uid" and "idmap gid" options from smb.conf.


IDMAP ALLOC OPTIONS

  ldap_base_dn = DN
     Defines the directory base suffix under which new SID/uid/gid mapping
     entries should be stored. If not defined, idmap_ldap will default to
     using the "ldap idmap suffix" option from smb.conf.

  ldap_user_dn = DN
     Defines the user DN to be used for authentication. If absent an
     anonymous bind will be performed.

  ldap_url = ldap://server/
     Specifies the LDAP server to which modify/add/delete requests should be
     sent. If not defined, idmap_ldap will assume that ldap://localhost/
     should be used.

  range = low - high
     Defines the available matching uid and gid range from which winbindd can
     allocate for users and groups. If the parameter is absent, Winbind fail
     over to use the "idmap uid" and "idmap gid" options from smb.conf.


EXAMPLES

  The follow sets of a LDAP configuration which uses a slave server running
  on localhost for fast fetching SID/gid/uid mappings, it implies correct
  configuration of referrals. The idmap alloc backend is pointed directly to
  the master to skip the referral (and consequent reconnection to the master)
  that the slave would return as allocation requires writing on the master.

	  [global]
	      idmap domains = ALLDOMAINS
	      idmap config ALLDOMAINS:default	   = yes
	      idmap config ALLDOMAINS:backend	   = ldap
	      idmap config ALLDOMAINS:ldap_base_dn = ou=idmap,dc=example,dc=com
	      idmap config ALLDOMAINS:ldap_url	   = ldap://localhost/
	      idmap config ALLDOMAINS:range	   = 10000 - 50000

	      idmap alloc backend = ldap
	      idmap alloc config:ldap_base_dn = ou=idmap,dc=example,dc=com
	      idmap alloc config:ldap_url     = ldap://master.example.com/
	      idmap alloc config:range	      = 10000 - 50000


NOTE

  In order to use authentication against ldap servers you may need to provide
  a DN and a password. To avoid exposing the password in plain text in the
  configuration file we store it into a security store. The "net idmap "
  command is used to store a secret for the DN specified in a specific idmap
  domain.
