I notice that for the Java SDK, INamespaceTrustedsignonProvider is available but I cannot seem to find this equivalent in the .NET SDK. Is it possible to configure a custom trusted sign on provider in .NET/C# or is that only available in Java?

I have reviewed the Cognos SDK Guide very carefully but its all Java based. I have also looked through all of the .NET packages from Cognos in Visual Studio's object explorer and have found nothing resembling INamespaceTrustedsignonProvider or anything to do with trusted sign on.
