+ <para>
+ 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.

+
+ <para>
+ 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.

+ <para>
+ The IDMAP database can be dumped to a text file as shown here:
+<screen>
+net idmap dump <full_path_and_tdb_filename> > 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:
+<screen>
+net idmap dump /var/lib/samba/winbindd_idmap.tdb > idmap_dump.txt

+ The IDMAP dump file can be restored using the following command:

+net idmap restore <full_path_and_tdb_filename> < dumpfile.txt
+</screen>
+ Where the Samba run-time tdb files are stored in the <filename>/var/lib/samba</filename> directory
+ the the following commands can be used to restore the data to the tdb file.
