Hi Martin,<br>
<br>
The Yahoo OP returns the OpenID URL of the authenticated user in the
response, so the RP does know who the user is. I believe that this is
consistent with the OpenID 2.0 spec.<br>
<br>
Thanks<br>

If you read "me.yahoo.com" as "me at Yahoo!" then it makes sense.
Yahoo!'s implementation is interesting in that (at least, when I last
checked, which was admittedly several months ago) even if you enter your
own identifer rather than the OP identifier it'll ignore the supplied
identifier and just verify the authenticated user. This has the same
effect as ignoring the user part of the email address; a user can be
unexpectedly switched to a different user account. This is particularly
troublesome when delegation is used.
