I have a really spooky problem.

I have NFAP 1 sp2 installed on a 5.1 sp5 server.

I am using domain authentication to a Windows 2003 domain, that was
recently
upgraded from 2000.

If I authenticate as myself (I was in the domain pre-upgrade), I can
access
the NFAP resources fine.

If I authenticate another user that I have just created, it fails.

I have tried deleting the user from ad and creating it as a copy of
me,
makes no difference.

This also happens if I try it from a Linux workstation.

I see a "Unknown user name or bad password" in the security event log
of
the veiwer, and the NDS account intruder locks after the appropriate
amount
of attemps, I see -1642 errors on nmasmon, however I am 100% certain
the
password is correct.

I have been looking at this for over a week now, hoping the penny will
drop.

Please help!!

Thanks

Jim
