Hi Tridge,

shouldn't we reject a request with a session but without signing,
if signing is negotiated as mendatory?

I think windows gives NT_STATUS_USER_SESSION_DELETED here...

Can you also change the client back to allow per smb2_session signing,
and we should only sign packets, which belong to a session.

We also need to take care of Oplocks breaks, from the server to the
client...
