A user with SuperUser rights can do anything in RT.
I think you know what it means to be an SuperUser. You don't need more rights. It's power and useless at same time.
Why is the SuperUser right bad:
- It's absolute power and power can break things, absolute power can break more things
- It's hard to check restrictions for other users
- Even if you are an administrator you should live in the same enviorment as your users to know how bad their live is
NOTE: Starting from version 3.2(or 3.4?) RT doesn't show users with SuperUser right in a ticket owner select-box.
NOTE: Think about this right as "right for main administrator(s)". Administrator can be an user of the RT at the same time, but you should grant him rights as you grant them to other users, because RT hides "super users" from interface in several cases. Now it's only select owner box(see previous note), but in the future version there is could be more such exceptions in RT because it's the right thing to do.
So try to avoid using SuperUser rights permanently, don't be self-assured as I am :) //RuslanZakirov
