+How often does this happen? 
+always
+
+Additional Information:
+In fact I need security manager for real project not for this test. I am
+using in .NET PrincipalPermission attribute in this usage:
+[PrincipalPermission(SecurityAction.Demand, Role = "test")] as critical
+part of remote proxy security.
