16 <refpurpose>Samba's idmap_ad Backend for Winbind</refpurpose>
20 <title>DESCRIPTION</title>
21 <para>The idmap_ad plugin provides a way for Winbind to read
22 id mappings from an AD server that uses RFC2307/SFU schema
23 extensions. This module implements only the "idmap"
24 API, and is READONLY. Mappings must be provided in advance
25 by the administrator by adding the posixAccount/posixGroup
26 classes and relative attribute/value pairs to the user and
27 group objects in the AD.</para>
31 <title>IDMAP OPTIONS</title>
35 <term>range = low - high</term>
37 Defines the available matching UID and GID range for which the
38 backend is authoritative. Note that the range acts as a filter.
39 If specified any UID or GID stored in AD that fall outside the
40 range is ignored and the corresponding map is discarded.
41 It is intended as a way to avoid accidental UID/GID overlaps
42 between local and remotely defined IDs.
46 <term>schema_mode = <rfc2307 | sfu ></term>
48 Defines the schema that idmap_ad should use when querying
49 Active Directory regarding user and group information.
50 This can be either the RFC2307 schema support included
51 in Windows 2003 R2 or the Service for Unix (SFU) schema.
58 <title>EXAMPLES</title>
60 The following example shows how to retrieve idmappings from our principal and
61 and trusted AD domains. If trusted domains are present id conflicts must be
62 resolved beforehand, there is no
63 guarantee on the order conflicting mappings would be resolved at this point.
65 This example also shows how to leave a small non conflicting range for local
66 id allocation that may be used in internal backends like BUILTIN.
72 idmap uid = 1000000-1999999
73 idmap gid = 1000000-1999999
75 idmap config CORP : backend = ad
76 idmap config CORP : range = 1000-999999
84 The original Samba software and related utilities
85 were created by Andrew Tridgell. Samba is now developed
86 by the Samba Team as an Open Source project similar
87 to the way the Linux kernel is developed.
