Hi all! I'm playing with customizing PAM at the moment and want to restrict the use of 'su' to members of group 'root' by enabling the feature in /etc/pam.d/su.
However, when I try to adduser myuser root it says group 'root' doesn't exist. (I checked in /etc/groups and /etc/gshadow, just to be sure - they're there allright.) Christian
