Question

I’m looking for the best/easiest way to add extensions to an existing protocol (can’t change the actual protocol easily) to allow the user to do windows authentication (NTLM?) in .NET. I looked at the AuthenticationManager class already but it requires that I use Web(Http)Request which isn’t an option. NegotiateStream is an option either as I want to integrate this into the existing protocol, not wrap it into a new one. Are there any options besides these two available to me ?

Answer 1

If you can only extend your protocol then one way to do this would be to write your own Stream class that you pass to NegotiateStream and then just take the messages that NegotiateStream gives you and put in your own protocol and give responses back to NegotiateStream through your Stream class. But if possbile, the easiest way would be to wrap your entire protocol (Stream) inside a NegotiateStream…
