The dummy service is a dummy implementation of the CollabNet Connect / link (also known as Integrated Application Framework or IAF) web service the TeamForge connector uses for authentication and authorization.
IAF provides functionality that requires all applications using it to implement a SOAP WebService interface; it also requires that the TeamForge server be able to connect to every integrated application. Since the connector doesn't actually make use of this extra functionality, we ship a dummy service that simply returns static, no-op responses for all web service calls.
