The authentication filter won’t work under tracing mode as tracer will wrap the auth filter as a FilterTracer which is just an IFilter. FilterGrouping.SelectAvailable can't select correct authentication filter with the wrapper.
In order to fix it, a strong typed tracer AuthenticationFilterAttributeTracer should be added and inherits from AuthenticationFilterAttribute.
