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 posixAc-
count/posixGroup classess and relative attribute/value pairs to the users and groups objects in 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 speci-
fied 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 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 and trusted AD domains. All is needed is to set default to
yes. If trusted domains are present id conflicts must be resolved beforehand, there is no guarantee on the order confliting 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 BULTIN.
[global]
idmap domains = ALLDOMAINS
idmap config ALLDOMAINS:backend = ad
idmap config ALLDOMAINS:default = yes
idmap config ALLDOMAINS:range = 10000 - 300000000
idmap alloc backend = tdb
idmap alloc config:range = 5000 - 9999

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