6 idmap_ad - Samba´s idmap_ad Backend for Winbind
7
9 The idmap_ad plugin provides a way for Winbind to read id mappings from
10 an AD server that uses RFC2307/SFU schema extensions. This module
11 implements only the "idmap" API, and is READONLY. Mappings must be
12 provided in advance by the administrator by adding the
13 posixAccount/posixGroup classes and relative attribute/value pairs to
14 the user and group objects in the AD.
15
17 range = low - high
18 Defines the available matching UID and GID range for which the
19 backend is authoritative. Note that the range acts as a filter. If
20 specified any UID or GID stored in AD that fall outside the range
21 is ignored and the corresponding map is discarded. It is intended
22 as a way to avoid accidental UID/GID overlaps between local and
23 remotely defined IDs.
24 schema_mode = <rfc2307 | sfu >
26 Defines the schema that idmap_ad should use when querying Active
27 Directory regarding user and group information. This can be either
28 the RFC2307 schema support included in Windows 2003 R2 or the
29 Service for Unix (SFU) schema.

32 The following example shows how to retrieve idmappings from our
33 principal and trusted AD domains. If trusted domains are present id
34 conflicts must be resolved beforehand, there is no guarantee on the
35 order conflicting mappings would be resolved at this point. This
36 example also shows how to leave a small non conflicting range for local
37 id allocation that may be used in internal backends like BUILTIN.

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