NAME

       idmap_hash - Samba's idmap_hash Backend for Winbind

DESCRIPTION

       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.

IDMAP OPTIONS

       name_map
           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
           supported.

EXAMPLES

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

                [global]
                idmap config * : backend = hash
                idmap config * : range = 1000-4000000000

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