You can specify this on the "su" pam rules in /etc/pam.d/su. There is a parameter for "not allowed" groups/users. (sorry for not telling the parameter, but I'm without my unix access right now to check for you). - Nelson -----Original Message----- From: pam-list-admin@redhat.com [mailto:pam-list-admin@redhat.com] On Behalf Of cnf Sent: Wednesday, December 18, 2002 5:49 PM To: pam-list@redhat.com i have 1 specific user (uid 400 *grin*) that i want to deny ALL login attempts to. so only direct console login would be allowed. i got it all working, the only thing i cant seem to get done is the su part. how do i tell pam, that ANY su attempt to the uid 400 is to be forbidden ? no matter is the su-ing user is in group wheel, or root himself, su to uid 400 needs to be denied. ideally i would want that user only to be able to log in on ttyS0, but for now i'll settle on solving the su prob :-) any suggestions ? cnf -- Please avoid sending me Word or PowerPoint attachments.
