+ <title>DESCRIPTION</title>
+
+ <para>The idmap_nss plugin provides a means to map Unix users and groups
+ to Windows accounts. This provides a simple means of ensuring that the SID
+ for a Unix user named jsmith is reported as the one assigned to
+ DOMAIN\jsmith which is necessary for reporting ACLs on files and printers
+ stored on a Samba member server.

+ <listitem><para>
+ Defines the available matching UID and GID range for which the
+ backend is authoritative. Note that the range acts as a filter.
+ Returned UIDs or GIDs by NSS modules that fall outside the range
+ are ignored and the corresponding maps discarded. It is intended
+ as a way to avoid accidental UID/GID overlaps between local and
+ remotely defined IDs.

+ <para>
+ Some NSS modules can return and handle UPNs and/or down-level
+ logon names (e.g., DOMAIN\user or user@REALM).
+ </para>
+ <para>
+ If this parameter is enabled the returned names from NSS will be
+ parsed and the resulting namespace will be used as the authoritative
+ namespace instead of the IDMAP domain name. Also, down-level logon
+ names will be sent to NSS instead of the plain username to give NSS
+ modules a hint about the user's correct domain.

+ <para>
+ This example shows how to use idmap_nss to obtain the local account ID's
+ for its own domain (SAMBA) from NSS, whilst allocating new mappings for
+ the default domain (*) and any trusted domains.
