NAME

       idmap_nss - Samba's idmap_nss Backend for Winbind

DESCRIPTION

       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.

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. 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.

       use_upn = <yes | no>
           Some NSS modules can return and handle UPNs and/or down-level logon names (e.g., DOMAIN\user or
           user@REALM).

           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.

           Default: no

EXAMPLES

       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.

                [global]
                idmap config * : backend = tdb
                idmap config * : range = 1000000-1999999

                idmap config SAMBA : backend  = nss
                idmap config SAMBA : range = 1000-999999
