16 <refpurpose>Samba's idmap_ldap Backend for Winbind</refpurpose>
20 <title>DESCRIPTION</title>
22 <para>The idmap_ldap plugin provides a means for Winbind to
23 store and retrieve SID/uid/gid mapping tables in an LDAP directory
28 In contrast to read only backends like idmap_rid, it is an allocating
29 backend: This means that it needs to allocate new user and group IDs in
30 order to create new mappings.
36 <title>IDMAP OPTIONS</title>
40 <term>ldap_base_dn = DN</term>
42 Defines the directory base suffix to use for
43 SID/uid/gid mapping entries. If not defined, idmap_ldap will default
44 to using the "ldap idmap suffix" option from smb.conf.
49 <term>ldap_user_dn = DN</term>
51 Defines the user DN to be used for authentication. If absent an
52 anonymous bind will be performed.
57 <term>ldap_url = ldap://server/</term>
59 Specifies the LDAP server to use for
60 SID/uid/gid map entries. If not defined, idmap_ldap will
61 assume that ldap://localhost/ should be used.
66 <term>range = low - high</term>
68 Defines the available matching uid and gid range for which the
69 backend is authoritative.
76 <title>EXAMPLES</title>
79 The following example shows how an ldap directory is used as the
80 default idmap backend. It also configures the idmap range and base
86 idmap config * : backend = ldap
87 idmap config * : range = 1000000-1999999
88 idmap config * : ldap_url = ldap://localhost/
89 idmap config * : ldap_base_dn = ou=idmap,dc=example,dc=com
93 This example shows how ldap can be used as a readonly backend while
94 tdb is the default backend used to store the mappings.
95 It adds an explicit configuration for some domain DOM1, that
96 uses the ldap idmap backend. Note that a range disjoint from the
97 default range is used.
102 # "backend = tdb" is redundant here since it is the default
103 idmap config * : backend = tdb
104 idmap config * : range = 1000000-1999999
106 idmap config DOM1 : backend = ldap
107 idmap config DOM1 : range = 2000000-2999999
108 idmap config DOM1 : read only = yes
109 idmap config DOM1 : ldap_url = ldap://server/
110 idmap config DOM1 : ldap_base_dn = ou=idmap,dc=dom1,dc=example,dc=com
111 idmap config DOM1 : ldap_user_dn = cn=idmap_admin,dc=dom1,dc=example,dc=com
118 <para>In order to use authentication against ldap servers you may
119 need to provide a DN and a password. To avoid exposing the password
120 in plain text in the configuration file we store it into a security
121 store. The "net idmap " command is used to store a secret
122 for the DN specified in a specific idmap domain.

130 The original Samba software and related utilities
131 were created by Andrew Tridgell. Samba is now developed
132 by the Samba Team as an Open Source project similar
133 to the way the Linux kernel is developed.
