I am getting an error when trying to authenticate using this strategy. Everything seems to matchup to Microsoft's documentation but I when I try to hit the auth route I am greeted with this screen:

Which doesn't tell me much. The URL, however, contains a bit more information:

https://login.live.com/err.srf?lc=1033#error=invalid_request&error_description=The+provided+value+for+the+input+parameter+'redirect_uri'+is+not+valid.+The+expected+value+is+'https://login.live.com/oauth20_desktop.srf'+or+a+URL+which+matches+the+redirect+URI+registered+for+this+client+application.&state=ddfdd0432fed588eb0196ded394722b7fe5df14ff379c650

According to the error message in the URL, my redirect_uri that I pass in the client options doesn't match one that I have defined in my created app, even though I've double and triple checked that it is the same URL.

Any ideas?
