>Description:
When root su's down to another account, even using -l to simulate a full login, they are unable to try to use passwd (as the user) to change their password, because passwd apparently checks realuid, and not effectiveuid. This also breaks usermin, which runs as a normal user, and has a password change module that uses passwd.
>How-To-Repeat:
As root, su -l to a user, then type passwd. You will get a "permission denied" error.
>Fix:
Always use passwd -l $username, or could someone submit a patch for passwd to correct this?
