Equivalent uid to root
Hi all
I have a strange problem on one my my AIX machines. We have created a user called testroot with the same UID as root (uid=0) by changing the uid of that user in the /etc/passwd file. I know that this is a security breach but this is a test system.
Now the strange thing that happens is that when i run
Code:
su -

to get the root prompt and then run
Code:
id

the command says that the id of the current user is testroot and NOT root, although having a uid of 0.
Strange enough, when i try to do some root tasks with that user like changing the password of another user on a HACMP cluster i am faced with an error message that only root can do this.
To my surprise, now even if i log on to the system with username root and the root password and run
Code:
id

it says that i am logged in as testroot!
Of course the only solution to this problem was to change the uid of that user to something else to regain my root privileges.
But still this is a very weird problem. Does anybody have a clue why this behavior occurs?
Thanks a lot in advance
