I would like to make a user super powerful, with almost all root rights but unable to touch a the root user (to change the password of the root).
My goal is to user "B" to manage my web server. The problem is user B need to able to run the
chmod commands on some files belonging to other users.
I tried to put B in root group or use visudo, but it's not enough.
I'm working an Centos 6 system.
If some body have ideas!
