I agree.  I think this actually broke about a week before the autoconf
merge, since I remember waiting for the merge in the hope that it would be
fixed.

Cool.

I'll include my smb.conf and anything else I can think of at the end of
this.  If you have a user profile or a system policy that gets downloaded
during the login, the problem doesn't appear.  If you have no user profile
(an empty profile directory) and there is no NTconfig.pol in the netlogon
share, then the user can log in and everything works nicely.

Andrew, I'll send a tcpdump to you late tonight (since I can't really kill
an entire lab until midnight) and I don't have a version of netmon that
will do promiscuous sniffing.

Have fun.
