Just to be sure, have logged out and in after that? > > 3. Added the user to the sudoers file with ALL permissions Remove or comment out the %wheel line in the sudoers file. It may take precedence over the user one. Also, remove (or comment out) the %wheel line in /etc/sudoers.d/sudo, if you have installed that file. But this shouldn't change the behavior of "su", only of "sudo". > > Where do I go from here?
