[Samba] password change error

[Gurnish Anand]

Hi,
  We migrated from redhat 7.1 to redhat 3 ES and ran into one road block 
after the other.
Most of them were solved except this last one.
Users cannot change their passwords and then I read somewhere that samba 
3.0 and MS KB828471 or 741 don't want to be friends. Then I upgraded my 
samba to be samba 3.0.7 (which i guess is the latest)....

Then I un-installed the KBB patch being accused. Still cannot change my 
passwords. Please adviceeeee............................. The following 
is my smb.conf
