Comment 7 for bug 639772

We (=Canonical IS) have had a few tickets filed for this problem on
summit.ubuntu.com as well.

In each case when I look at the user's accounts, there is a Django
user "foo" and a user "foo2". User "foo" has no password set and no
matching row in django_openid_auth_useropenid, but user "foo2" does
have such a row and also no password set. Switching the usernames of
the Django accounts around fixes (or "fixes" ... but so far so good)
the symptoms for that particular user.
