It's nothing wrong with that.
I just wanted to study how SMB signing is done and the NTLMSSP stuff
confuses me. The reason for my question was that, by looking into the
CIFS-SNIA tech.ref,  it seems that SMB signing should work with just
NT/LM (v1 ?) authentication.

Another question: Does anyone know if the MAC-key (used for
the signing) is the same as the NT/LM-session key ?

Cheers, Tobbe
