Is it possible to have an 'su only' user account ?
Issue
- Is there a way to have su (switch user) as the only means of becoming a user?
- Trying to prevent a generic account from logging in at both the GUI (KDE, GNOME, etc) and at the console (such as at runlevel 3).
- Once a regular user logs in they could su to the 'su only' user.
Environment
- Red Hat Enterprise Linux 4 or 5
- pam
