I've been using Samba 2.2.7 as a PDC for about 3 or 4 days now, logging
on perfectly well from WinXP to RH9. I now have been told by the WinXP
machine that my password has expired. Can anyone riddle me why this is
happening? Is it a setting in smb.conf that I have to change? Or is is a
WinXP security policy buggering things up? Could it be the mysterious
PAM restrictions?

Any help = much appreciated.
