[Samba] Samba authentication against Linux-based Kerberos

please consider the following situation in a heterogenous, Windows
Server-less network, where users use both Windows and Linux:

- On Windows users authenticate against a Samba 3.3.2 PDC with tdbsam
- On Linux users authenticate against a combination of OpenLDAP and

This, of course, brings up the old problem that users have to
synchronise their passwords manually for both Windows and Linux.

The ideal solution would be that Samba would just support authentication
against Linux-based Kerberos, but (correct me if I'm wrong) that doesn't
seem possible with Samba3.

Is there anything else that can be done? So if users on Windows can't
use Linux-based Kerberos for SSO, maybe there is at least a way for
users to change their passwords on one OS and get it automatically
synced for the other (i.e. if a user changes his password on a Windows
machine it gets automatically changed for his Linux account as well and
vice versa)?
