Linux/Unix Root Passwords and User Advice/Help Needed
Group,I am looking for the best way or options on how to configure users and user permissions on my linux server.
This is how I currently have things setup
Username --> User Password --> = (underprivileged user)
If they want root access and I have given them the root password then they do this
Username --> User Password --> SU --> Root Password --> = (root access user)
..
This below is how I would really like to do it , but I am told that this is not possible
Username --> User Password --> =(underprivileged user)
If they want root access I would create a secondary (other than main root password) third, or fourth root password that is just for that user and then let them SU to root with that Secondary root password.
Username --> User Password --> SU --> Secondary root password --> = root access user
My reasons for doing it this way is so that if a user leaves the picture I dont have to worry about changing the main root password because someone is no longer in the picture and have to change the root password in fear that they may try to return and ruin or destroy something in the server after they have left.
Doing it the way I described all I would have to do is delete their secondary root password and im done.
If a new user comes along all I have to do is create a normal user name, and create another secondary root password for that user.
I never have to worry about the main root password being given out to anyone other than me.
My main question is does anyone know of any websites or books that would give me A LOT of detailed information on all the ins and outs of Root passwords, and users and groups, and etc, so that I can learn more about what I can do and what my options are in regards to this and as well as how to actually do and set it all up?
I am using Red Hat Linux Enterprise WS.
Thanks much
Doug
