[root@localhost ~]# smbldap-passwd kennyz
Changing UNIX and samba passwords for kennyz
New password: <enter pass>
Retype new password: <enter pass>
No errors returned. User is able to login with new password.
Commented out "unix password sync = yes". Still same result..."You do
not have permission to change your password."
Thank you for your help! We'll keep trying...
