Thinking about it more, and checking the code, yes I'm wrong. Just
not sure why I even thought that in the first place. Been staring
at this for too long I guess.

I'll add a connection pool to the mschap winbind code so it
doesn't have threading issues... as always annoying the issues
only show up under load, not in normal testing.
