[Samba] "You do not have permission to change" password issue with XP clients

[Brett Charbeneau]

Greetings all

I'm running Samba 3.0 on an Ubuntu box as a PDC and I'm having trouble changing 
passwords with XP clients - here's my smb.conf http://pastebin.com/m1bb6d4a6

I've played with a variety of "passwd chat" settings but no joy. I am trying to 
use pam_cracklib.so - here's my /etc/pam.d/common-password file: 
http://pastebin.com/m1a1d5f89

I've tried the suggestions in this thread, but no luck:

Any hints? I'd be very grateful for any suggestions anyone has the time to 
offer!
