This is all great and works fine. If a user1 is logged in to a system. Knows the password of user2 and issues the command "su" to be that user2 on that same system. This is not allowed because the user2 does not have HBAC rules for that system. This is as expected. But if the user root tries the "su" command to be user2 is works despite the fact that user2 has no HBAC rule for that system. Why does this works? Is there a way to prevent this? Or is this something in "su" that it works like the way it does? Best regards, Jurriën This message (including any attachments) may contain information that is privileged or confidential.
