I think you're missing the point of that particular code. It is called on
connection disconnect and those assignments are only made if NTLM has been
used.

NTLM is connection based and thus it must be re-negotiated at next connect no
matter what you or I like!

It didn't do what? The assignment has been there for a year, that is not new.

But sure, bugs still creap in... Can you perhaps tell us how you get to see
this problem so that I can write up a test case for it?

Yes. But using AUTH_ANY with a blank user is not very good if something else
than NTLM was picked!
