Removing the Everyone group from the Cognos System Administrators role
By default all authenticated users are members of the Everyone group in Cognos, and members of this group have the System Administrators role in Cognos. This grants all users administrator rights in Cognos by default. This procedure assigns the EMM_ Report_System_Admin_User group or Reports_System_Role role as administrators in Cognos, and removes the Everyone group from the Cognos System Administrators role.
