Hi Rikona,

As Sarunas mentioned, you will have to edit the sudoers file via visudo;
granted, you will have to be root first to be able to do that.

I must confess that, as you mentioned, at first, I also had the same
principle: add a user to a group and it will share the group's
privileges/restrictions. But that only happens in the Windows world. Since
I am confessing, I have to admit I have no idea how group membership takes
effect in the *nix world.

Hope this at least gets you need.

Good luck!
