disable AskUser in OpenId Provider

Question

I create OpenId Provider by DotNetOpenAuth Library.

I use OpenIdProviderMvc project that found on sample of DotNetOpenAuth and customized it.

Now I have 2 question:

• How can I remove AskUser step?
• How can i signout in provider after response to RP?

Answer 1

Skipping the ask user step is as easy as changing the OpenIdController.ProcessAuthRequest method so that instead of redirecting to the AskUser action, it always (effectively) follows the path as if AutoRespondIfPossible returned true.

You can effectively sign the user out "after" response to RP by clearing the cookie in the same redirect instruction to the browser. So before returning from the ProcessAuthRequest method, try:

FormsAuthentication.SignOut();

If that doesn't work, you may have to do the cookie manipulation yourself as described in this question.
