Disqus shows three fields on their login page: "Username or Email", "Password", and "OpenID URL". If you put
https://openid.stackexchange.com into "OpenID URL" (as instructed on SE's blog) and click Login, you're rejected with "We couldn't log you in. Please check what you've entered." What is the correct approach to log in to Disqus with a StackExchange OpenID?
(My understanding about OpenID is that I should only be typing the StackExchange OpenID endpoint URL into this form. Correct me if I'm wrong. Also, please forgive the relatively newb question and that I couldn't find a better place to ask.)
