I am trying to set the redirect_uri for the facebook login with Asp.Net Identity. However, the GetExternalLogin REST method in the AccountController is only triggered if the redirect_uri is '/'. If I add anything else it does not trigger GetExternalLogin, the browser only shows error: invalid_request.
However the url contains the redirected parameter as it should e.g. if I add the redirect_uri as http://localhost:25432/testing
the response URL looks like this:
http://localhost:25432/api/Account/ExternalLogin?provider=Facebook&response_type=token&client_id=self&redirect_uri=http%3A%2F%2Flocalhost%3A25432%2Ftesting&state=0NctHHGq_aiazEurHYbvJT8hDgl0GJ_GGSdFfq2z5SA1
and the browser window shows: error: invalid_request
Any idea why this works only when redirecting to '/' but not to any other url´s?
