[Samba] Users unable to change their passwords using 200/XP change password dialouge.

[Alan Munday]

I've just found out today that my system won't let users (2000 and XP
clients) change their passwords.
>From their consoles they get permission denied messages.

Looking at the logs its clearly a Samba/PAM interaction issue but all looks
OK in the pam.d directory.

I've spent a few hours searching online but can't find anything that match's
this scenario.

Extract from users log follows:
