Ab der Samba Version 3.3.0 hat sich die Struktur des passdb backends tdbsam grundlegend geändert. Deshalb sollte vor einem Upgrade unbedingt die releasenote beachtet werden.

General changes
===============
The passdb tdbsam version has been raised as among other things the RID counter
has been moved from the winbindd_idmap.tdb to the passdb.tdb file to make
"passdb backend = tdbsam" working in clustered environments.
Please note that an updated passdb.tdb file is _not_ compatible with Samba
versions before 3.3.0! Please backup your passdb.tdb file if
you use "passdb backend = tdbsam". That can be achieved by running
'tdbbackup /etc/samba/passdb.tdb'
before the update.
