NAME

       idmap_hash - DO NOT USE THIS BACKEND

DESCRIPTION

       DO NOT USE THIS PLUGIN 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.
       The module divides the range into subranges for each domain that is being handled by the
       idmap config. The module needs the complete UID and GID range to be able to map all SIDs.
       The lowest value for the range should be the smallest ID available in the system. This is
       normally 1000. The highest ID should be set to 2147483647. A smaller range will lead to
       issues because of the hashing algorithm used. The overall range to map all SIDs is 0 -
       2147483647. Any range smaller than 0 - 2147483647 will filter some SIDs. As we can
       normally only start with 1000, we are not able to map 1000 SIDs. This already can lead to
       issues. The smaller the range the less SIDs can be mapped. We do not recommend to use this
       plugin. It will be removed in a future release of Samba.

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 = 1000-2147483647

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