[Samba] samba 3.6 DC migration to CTDB cluster

[Marko Bencek]

I am trying to migrate samba domain controller (version 3.6, passdb
backend = tdbsam) to a new clustered environment with CTDB (same samba
version). I have a functional ceph storage and the ctdbd configured
according to the documentation.

However, all available guides are for the fresh installations and I
can't migrate current data into the CTDB.

Simply restoring tdb database into the CTDB doesn't work and it ends
with the following error: '2015/05/25 22:25:04.849302 [ 5636]: Invalid
version of database dump. File is version 7308332182664266836 but
expected version was 1' Converting tdb database with ltdbtool doesn't
bring any joy too.

How to import tdb samba databases into the ctdb?
Thanks,
Marko
