If you were to connect to Samba using the CIFS VFS client (when it gets
kerberos support) or smbmount from Samba 3.0 (slightly modified), you
can pass a kerberos ticket to the server.
The server can be 'trusted for delegation' by the KDC, which means that
it can take the ticket passed from the client, and use it in the
client's place. (In this case to acquire access to DCE resources).
I'm not sure why you would want to do this however, when you could just
mount the DFS stuff onto Linux (I assume there is a client...).
This would be more interesting with Win2k clients doing kerberos
authentication and getting access to previously unix-only resources.
