I'm using the OpenId module (included in core v7) but can't link an OpenId to an existing account. Every time I try to add it an error occurs:
Sorry, that is not a valid OpenID. Ensure you have spelled your ID correctly.
I'm trying to connect using a Google profile. The URL I'm trying is "https://profiles.google.com/x" (x => my id).
Has anybody succeeded in doing this?
