IDMAP_AD(8)
NAME
idmap_ad - Samba's idmap_ad Backend for Winbind
DESCRIPTION
The idmap_ad plugin provides a way for Winbind to read id mappings from
an AD server that uses RFC2307/SFU schema extensions. This module
implements only the "idmap" API, and is READONLY. Mappings must be
provided in advance by the administrator by adding the
posixAccount/posixGroup classes and relative attribute/value pairs to
the user and group objects in the AD.
IDMAP OPTIONS
- range = low - high
- Defines the available matching UID and GID range for which the
backend is authoritative. Note that the range acts as a filter. If specified any UID or GID stored in AD that fall outside the range
is ignored and the corresponding map is discarded. It is intended
as a way to avoid accidental UID/GID overlaps between local and
remotely defined IDs. - schema_mode = <rfc2307 | sfu >
- Defines the schema that idmap_ad should use when querying Active
Directory regarding user and group information. This can be either the RFC2307 schema support included in Windows 2003 R2 or the
Service for Unix (SFU) schema.
EXAMPLES
- The following example shows how to retrieve idmappings from our
principal and trusted AD domains. If trusted domains are present id
conflicts must be resolved beforehand, there is no guarantee on the
order conflicting mappings would be resolved at this point. This
example also shows how to leave a small non conflicting range for local id allocation that may be used in internal backends like BUILTIN. - [global]

Andrew Tridgell. Samba is now developed by the Samba Team as an Open
Source project similar to the way the Linux kernel is developed.
