Samba log on limit

[Neal Schilling]

If I'm not mistaking, the protocol specifications say "If a server 
receives a transport establishment request from a client with which it 
is already  conversing, the server may terminate all other transport 
connections to that client.  This is  to recover from the situation 
where the client was suddenly rebooted and was unable to  cleanly 
terminate its resource sharing activities with the server." Although 
this is referring to a computer, not a single user, it could be extended 
to include this and still be within the designation of the protocol. 
This would also be an indicator that someone else is using your account, 
as your connection would be terminated.
