idmap_hash - DO NOT USE THIS BACKEND
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.
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.
The following example utilizes the idmap_hash plugin for the idmap and nss_info
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
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.
