I have a gmail and a google email (@google.com). And I want to be able to login to Stackoverflow using either of them.
I authenticated with my gmail account. I tried add more logins using my own openID URL https://google.com/accounts/o8/site-xrds?hd=google.com. It will redirect to Google's internal authentication page. But after the standard authorization page, I see an error reads:
Unable to log in with your OpenID provider: Error occurred while sending a direct message or getting the response.
I can live with only logging in with my gmail account. But it would be really nice if I can use either of them to authenticate.
