<title>DESCRIPTION</title>
|
|
|
|
<para>The idmap_ldap plugin provides a means for Winbind to
|
|
store and retrieve SID/uid/gid mapping tables in an LDAP directory
|
|
service.
|
|
</para>
|
|
|
|
<para>
|
|
In contrast to read only backends like idmap_rid, it is an allocating
|
|
backend: This means that it needs to allocate new user and group IDs in
|
|
order to create new mappings.

<para>
|
|
The following example shows how an ldap directory is used as the
|
|
default idmap backend. It also configures the idmap range and base
|
|
directory suffix. The secret for the ldap_user_dn has to be set with
|
|
"net idmap secret '*' password".
|
|
</para>

<programlisting>
|
|
[global]
|
|
idmap config * : backend = ldap
|
|
idmap config * : range = 1000000-1999999
|
|
idmap config * : ldap_url = ldap://localhost/
|
|
idmap config * : ldap_base_dn = ou=idmap,dc=example,dc=com
|
|
idmap config * : ldap_user_dn = cn=idmap_admin,dc=example,dc=com
|
|
</programlisting>
|
|
|
|
<para>
|
|
This example shows how ldap can be used as a readonly backend while
|
|
tdb is the default backend used to store the mappings.
|
|
It adds an explicit configuration for some domain DOM1, that
|
|
uses the ldap idmap backend. Note that a range disjoint from the
|
|
default range is used.

# "backend = tdb" is redundant here since it is the default

<title>NOTE</title>
|
|
|
|
<para>In order to use authentication against ldap servers you may
|
|
need to provide a DN and a password. To avoid exposing the password
|
|
in plain text in the configuration file we store it into a security
|
|
store. The "net idmap " command is used to store a secret
|
|
for the DN specified in a specific idmap domain.

by the Samba Team as an Open Source project similar

to the way the Linux kernel is developed.
