While MS-SMB2 2.2.3 says NEGOTIATE_CONTEXT in the NegotiateContextList array 
must be 8-byte-aligned, so NegotiateContextList may include padding between the 
hold the size of Data, which does not include padding. So from that, this is a 
server bug.

Otoh, Windows clients are probably able to connect to the server, so they seem 
to be more forgiving.

I guess we need clarification from dochelp at MS on the matter.
