Arrgggh. Andrew, I hate you. My brain now *REALLY HURTS*
trying to understand this horror :-).

Am I correct in thinking that this is when the client is
using ntlmv2 auth, we correctly can use ntlm2 session
security, but when the client is not using ntlmv2, we
don't correctly handle the ntlm2 session security (which
is valid in the spec) ?

I feel ill now :-).
