In a simple app i have three user roles “ Developer” , Administrator” and “User” Developer access rights are more than Administrator, i.e some extra configuration pages which are useless for Administrator or we can say Developer rights=Administrator right+extra right.. As per my knowledge only Administrator can view all the selection list of user roles and in my case Developer also can, But I want to exclude the Developer User role from the list so that Administrator can’t assign, delete or edit it…
You simply need to remove developers from the roles Administrators manage
Open Project security
Go under user roles
Edit the administrator user role
Under User Management, tick Selected and tick all roles but developers
Your admins should no longer be able to manage developers.
