Betreff: Re: AW: [Samba] Error: You do not have permission to change your
password

  Using that from the command line I'm able to change the user's
password and successfully login. However, that didn't solve my problem
when the user tries to change their password and I receive "You do not
have permission to change your password."

Thanks for your help thus far.
