<title>DESCRIPTION</title>
|
|
<para>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.

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.
