[Samba] authenticating using winbindd against NT4 domain fails
Since version 3.0.23b, I have been having trouble getting Windows & OSX
users to access an NT domain member server running FreeBSD 5.4. It is now at
3.0.23c (installed this morning the 5th).

I understand that the winbind behavior has changed in 3.0.23x (or 3.0.22?)
but it was my impression that nothing had changed in the way a Samba member
server authenticates against a NT4 PDC using winbindd. What might I be doing
wrong here?
