       idmap_hash - Samba's idmap_hash Backend for Winbind


       The idmap_hash plugin implements a hashing algorithm used to map SIDs
       for domain users and groups to 31-bit uids and gids, respectively. This
       plugin also implements the nss_info API and can be used to support a
       local name mapping files if enabled via the "winbind normalize names"
       and "winbind nss info" parameters in smb.conf.


           Specifies the absolute path to the name mapping file used by the
           nss_info API. Entries in the file are of the form "unix name =
           qualified domain name". Mapping of both user and group names is


       The following example utilizes the idmap_hash plugin for the idmap and
       nss_info information.

                idmap backend = hash
                idmap uid = 1000-4000000000
                idmap gid = 1000-4000000000

                winbind nss info = hash
                winbind normalize names = yes
                idmap_hash:name_map = /etc/samba/name_map.cfg


       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.
