How to force 'sudo' usage ? disabling root ?

[bcostacurta]

Hello,

I would like to force my users to use 'sudo'
How can i do this ?
Do I need to disable root ?
Note: distributions like Ubuntu do not have a (not at all or only inactive ?) root user.

My concern is more educational than security, and I suppose that a 'full' sudo user can bypass this, but at least this will be made intentionally by the user.

Thanks.
Bye,
Bruno

Which version of Fedora are you using? root login in GUI has been disabled in latest version of Fedora, 10.

Its easy to disable root login in earlier versions. Which Desktop Environment are you using?

You have to add users in sudoer file for assigned sudo privileges to all or selective Administrative tools.

The root user is still present, but has its password encrypted so that it cannot be retrieved. If you have /etc/sudoers set up correctly it would be as simple as changing the root password and educating your users on the new procedure.

Precisely, I'm using CentOS 5.2

Thanks for attention.
