Can root ID be duplicated
Hi,

I have the root id and the uid is always 0 for the root. Can i create another user say admin with the uid as 0? If so will it have the same privilege as that of user.

Will there be any effect while doing this?

We can create a such user id with duplicate uid of root. But don't know the effect of it

It will still be the same user. The UNIX kernel and filesystems identify users by the uid, not the name.

So if i forgot the root password, can i login through admin (uid=0) id and have all the rights like root.

Of course, you will have full root privilege with that user cause your ID is 0, but single user mode is the better way to recover a lost root password

being an extremely lazy SA, i would not go to single user mode when a quick reset of the root password can be done by another root account ... going to single user mode just to recover a lost password takes the machine off line and involves a lot more steps to do the same thing as what is available already ...

on an audit perspective, you will invite alot of questions from the auditor for having 2 ids with number 0.
