       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.

Samba 4.22.3-Ubuntu-4.22.3+dfs                     07/21/2025                                      IDMAP_HASH(8)

       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 /etc/samba/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.

       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

       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 "unixname = qualifieddomainname". Mapping of both user and group names is
           supported.
