<title>DESCRIPTION</title>
21
<para>The idmap_hash plugin implements a hashing algorithm used to map
22
SIDs for domain users and groups to 31-bit uids and gids, respectively.
23
This plugin also implements the nss_info API and can be used
24
to support a local name mapping files if enabled via the
25
"winbind normalize names" and "winbind nss info"
26
parameters in smb.conf.
31
<title>IDMAP OPTIONS</title>
37
Specifies the absolute path to the name mapping
38
file used by the nss_info API. Entries in the file
39
are of the form "<replaceable>unix name</replaceable>
40
= <replaceable>qualified domain name</replaceable>".
41
Mapping of both user and group names is supported.

<title>EXAMPLES</title>
49
<para>The following example utilizes the idmap_hash plugin for
50
the idmap and nss_info information.
56
idmap uid = 1000-4000000000
57
idmap gid = 1000-4000000000
59
winbind nss info = hash
60
winbind normalize names = yes
61
idmap_hash:name_map = /etc/samba/name_map.cfg

The original Samba software and related utilities
70
were created by Andrew Tridgell. Samba is now developed
71
by the Samba Team as an Open Source project similar
72
to the way the Linux kernel is developed.
