I'm writing a Windows RT / Windows Store app and the service that the app wraps authenticates using OAuth. Previously the OAuth requests were going to my server over HTTP, but I wanted to instead upgrade to HTTPS. I am using a self-signed certificate for the SSL communications to my server. However it appears that the WebAuthenticationBroker fails (without returning from the AuthenticateAsync method).
I thought it was working when I tested in fiddler but to decrypt traffic I believe fiddler intercepts so I can't really inspect what webauthenticationbroker is doing (when using fiddler, and telling fiddler to ignore self-signed concerns, the app works as intended)
