+       The IDMAP UID to SID, and SID to UID, mappings that are created by <command>winbindd</command> can be
+       backed up to a text file. The text file can be manually edited, although it is highly recommended that
+       you attempt this only if you know precisely what you are doing.

+       An IDMAP text dump file can be restored (or reloaded). There are two situations that may necessitate
+       this action: a) The existing IDMAP file is corrupt, b) It is necessary to install an editted version
+       of the mapping information.
+       </para>
+
+       <para>
+       Winbind must be shut down to dump the IDMAP file. Before restoring a dump file, shut down
+       <command>winbindd</command> and delete the old <filename>winbindd_idmap.tdb</filename> file.

+       The IDMAP database can be dumped to a text file as shown here:

+net idmap dump &lt;full_path_and_tdb_filename&gt; &gt; dumpfile.txt
+</screen>
+       Where the Samba run-time tdb files are stored in the <filename>/var/lib/samba</filename> directory
+       the the following commands to create the dump file will suffice:

+net idmap dump /var/lib/samba/winbindd_idmap.tdb &gt; idmap_dump.txt

+</screen>
+       Where the Samba run-time tdb files are stored in the <filename>/var/lib/samba</filename> directory
