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 mod-
       ule 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  allo-
	  cation range due to the fact that the same backend will store and retrieve SID/uid/gid mapping entries. If the parameter is absent, Win-
	  bind 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://local-
	  host/ 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, Win-
	  bind 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  recon-
       nection 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.
