22         <para>The idmap_ldap plugin provides a means for Winbind to
23         store and retrieve SID/uid/gid mapping tables in an LDAP directory
24         service.  The module implements both the &quot;idmap&quot; and
25         &quot;idmap alloc&quot; APIs.

146         <para>In order to use authentication against ldap servers you may
147         need to provide a DN and a password. To avoid exposing the password
148         in plain text in the configuration file we store it into a security
149         store. The &quot;net idmap &quot; command is used to store a secret
150         for the DN specified in a specific idmap domain.
