Steps to reproduce:
- Log in to a private beta site you've committed to with the OpenID you used on Area51.
- On the beta site, add an alternate OpenID to your account.
- Logout from the beta site
- Attempt to log back in using the alternate OpenID you just added
Expected: you are logged in to your account.
Actual: you are shown a message saying that the site is in private beta, meaning that you can only login with your Area51 OpenID.
This is a small bug (although it might be a feature request) that should be easy to fix. I guess the alternate OpenIDs just aren't being added into the OpenID whitelist.
