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 "
qualified domain name".
Mapping of both user and group names is supported.
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
