I need to create a new role for an "Application Admin" which should have all the rights of a regular admin except "Create roles".
If I allow "Change site configuration" and prevent/prohibit "Create and manage roles" I am still able to create a new role.
Is that a normal behavior?
It seems to me that there is a bug in admin/roles/manage.php
I made also changes in a teacherrole and it wasn't saved. See http://moodle.org/mod/forum/discuss.php?d=60421
