13 <refpurpose>Samba's idmap_ad Backend for Winbind</refpurpose>
17 <title>DESCRIPTION</title>
18 <para>The idmap_ad plugin provides a way for Winbind to read
19 id mappings from an AD server that uses RFC2307/SFU schema
20 extensions. This module implements only the "idmap"
21 API, and is READONLY. Mappings must be provided in advance
22 by the administrator by adding the posixAccount/posixGroup
23 classess and relative attribute/value pairs to the users and
24 groups objects in AD</para>
28 <title>IDMAP OPTIONS</title>
32 <term>range = low - high</term>
34 Defines the available matching uid and gid range for which the
35 backend is authoritative. Note that the range acts as a filter.
36 If specified any UID or GID stored in AD that fall outside the
37 range is ignored and the corresponding map is discarded.
38 It is intended as a way to avoid accidental UID/GID overlaps
39 between local and remotely defined IDs.
44 <title>EXAMPLES</title>
46 The following example shows how to retrieve idmappings from our principal and
47 and trusted AD domains. All is needed is to set default to yes. If trusted
48 domains are present id conflicts must be resolved beforehand, there is no
49 guarantee on the order confliting mappings would be resolved at this point.
51 This example also shows how to leave a small non conflicting range for local
52 id allocation that may be used in internal backends like BULTIN.
57 idmap domain = ALLDOMAINS
58 idmap config ALLDOMAINS:backend = ad
59 idmap config ALLDOMAINS:default = yes
60 idmap config ALLDOMAINS:range = 10000 - 300000000
62 idmap alloc backend = tdb
63 idmap alloc config:range = 5000 - 9999
71 The original Samba software and related utilities
72 were created by Andrew Tridgell. Samba is now developed
73 by the Samba Team as an Open Source project similar
74 to the way the Linux kernel is developed.
