          A return of true does not guarantee successful authorization. A
          return of false indicates that it is known all methods in this
          session will result in a PermissionDenied. This is intended as a
          hint to an application that may opt not to offer lookup
          operations to unauthorized users.
  
          return: (boolean) - false if lookup methods are not authorized,
                  true otherwise
          compliance: mandatory - This method must be implemented.
