act as OPs (Flickr, AOL, etc.) still do not have https:// identity URLs, so

RPs cannot leverage cheap, ubiqitous SSL/TLS PKI to help thwart the more

obvious DNS and MITM/phishing attacks.



BTW, whoever maintains http://openid.net/get/ should probably change the

Yahoo information to "https://me.yahoo.com/" since that works and, unlike

http://openid.yahoo.com/, uses SSL/TLS.



Thanks,



Peter

<p class=3DMsoPlainText>If OpenID is to be used in consort with ws-trust
