[rt-users] Auto created user has a privileged status.

[David Michal]

Helo,
when a non-existing user is logging to the RT through web, then RT 
create user account for him. That's cool and I want it. But the new 
created user have got a privileged status, so he's going to be a staff 
member, and that's not cool. :) Please anybody know what I have to 
configure, to have new users in non-privileged system group?
Thanks,
David
