samba - Nov 2005 - Modify and backup winbindd_idmap.tdb

Hello list,

Is there a possibility to add entries to the winbindd_idmap.tdb manually?
I know I can use tdbdump to see the entries, but is there a chance to modify?

My problem is I have to map some uid to some Windows SID without using LDAP. On
the other hand new user not having any uid in linux should map to the range of
uid I defind by using

idmap uid = 10000-20000

2nd Question:

Is it possible to backup winbindd_idmap.tdb by just copy the file and use this
file to replace in case of corruption of the original file?

Greetings

Markus

Samba and Wnibind are designed to upgrade cleanly.
And this works for me.  I've had one report of problems
but have not been able to confirm that as of yet.

use net idmap dump and net idmap restore to dump the db, modify it and
restore, but be extremely careful in what you do.

not with tdbdump, see above

no, you may have a corrup file as outcome, use tdbbackup that guarantees
a complete database traversal record by record.

Simo.
