If you install System Center 2012 Configuration Manager, there is no additional configuration because the Active DIRECTORY user account used to install Configuration Manager is automatically assigned to the Full Administrator security role, assigned to All Scopes, and has access to the All Systems and All USERS and User Groups collections. HOWEVER, if you want to provide full administrative permissions for other Active Directory users to access System Center 2012 Configuration Manager, CREATE new administrative users in Configuration Manager using their Windows accounts and then ASSIGN them to the Full Administrator security role.
