Full Discussion: Su root or login root
Operating Systems Linux Red Hat Su root or login root Post 302895025 by sea on Friday 28th of March 2014 09:22:45 AM

The root user is no regular user.
And for security issues, its not supposed (on any 'real' *nix system != *ubuntu (did suse remove that option yet?)) to login to GUI.

You might have better luck, to remove the users from admin group (adm) so they wont have permission to login root.

Further a closer inspection of /etc/passwd as already suggested seems a good idea.
You dont need to limit root, leave root's values alone, you need to limit the user!

securetty

SECURETTY(5)						     Linux Programmer's Manual						      SECURETTY(5)

NAME

       securetty - file which lists terminals from which root can log in

DESCRIPTION

       The file /etc/securetty contains the names of terminals (one per line, without leading /dev/) which are considered secure for the transmis-
       sion of certain authentication tokens.

       It is used by (some versions of) login(1) to restrict the terminals on which root is allowed to login.  See login.defs(5) if  you  use  the
       shadow suite.

       On  PAM	enabled  systems,  it  is  used  for  the  same purpose by pam_securetty(8) to restrict the terminals on which empty passwords are
       accepted.

FILES

       /etc/securetty
