Can someone please point me in the right direction. When I try so 'su' to a different user than the one I am currently logged in as, I get the following error.
Account is Disabled -- See Account Administrator.
I can 'su' as root, but not as a user. I have come across this problem before and for the life of me I can't remember what the issue was.
What OS? Are you going from root to the other user account (no password should be asked).
I searched some of your responses from old messages and noted you mentioned HP-UX - if this is the OS you are working on could it have something to do with the SU_ROOT_Group in /etc/default/security ?
