Kelam,

Setting a alias such as you suggest brings about a problem - if the alias is set and the user still does su -, the system will think the user wants to su - to userID - (which it then informs you does not exist).

medusa% alias su 'su -'
medusa% su
Password:
Sun Microsystems Inc. SunOS 5.8 Generic February 2000
[root@medusa]:/root
# exit
medusa% su -
su: Unknown id: -


You at least read the post more carefully than I as I thought the PzYon wanted it so they could not do su -. The logic in the script could still be done. The alias solution might work but a more intracate solution would be needed.
