The SourceForge signon page says I can associate an OpenID with my existing SourceForge account: https://sourceforge.net/account/login.php
- I enter my currently-signed-in SourceForge account password
- I select the custom OpenID URL and enter
- I'm redirected to
https://openid.stackexchange.com/account/login?<session key bits>
- I enter my openid.stackexchange.com login information there
I get the error message:
Cannot Complete Login
Detected an attempt to send an assertion when the identifier (https://openid.stackexchange.com/) is not owned by the logged in user.
I don't understand what that means.
