[Samba] CIFS Session transfer

Hi Andrew,

Thanks for your inputs. 

I agree that we need a server preying for other servers. 

The catch here is there should not be any need to change the CIFS client.
The solution should work with any CIFS client without having to change the
CIFS client or without having to add some service over CIFS client. I will
only have the liberty to change the CIFS server implementation to provide
this solution. All the CIFS servers participating in this solution can be
aware of this extensions to the CIFS behavior.

This is not possible, excecpt by MSDFS.  In theory, it might be possible
for one host to hijack a connection to another, but it would need to
have full vuid/tid/fd tables before it would even start to look like it
worked.   The closest I can come is the suggestion (mad earlier) that
you could have one server 'proxy' for another, or a 'frontend' server
proxying for a number of backends.  (I understand some cluster
arrangements do this).
