I think you hit the nail on the head, both the identity URL and the OP
endpoint URL need should be using SSL. Depending on the URL scheme of
the OP, this may mean needing a wild-card certificate (like MyOpenID.com
does) while other schemes could host everything off of one domain
(MediaWiki URLs for example).

This seems to be a good place to reintroduce something that I discovered
last week. It does seem like a problem that the OpenID community needs
to address, although how it's addressed remains to be seen. I did put
something in the user-experience wiki page about it.

But prefixing the string with https:// (whether implicitly by a redirect
or explicitly by user typing) doesn't work! Here's how to see this.
Get an OpenID identifier from protectnetwork.org. It will be of the
Try logging into the wiki right here for this community.
Type in your OpenID identifier as https://user.protectnetwork.org.
It won't work; you won't be logged in.
I suspect that the reason that it doesn't work is that the SSL
certificate for the protectnetwork OP says that its name is
That doesn't match user.prot... so that verification fails during the
Someone did suggest that the consequences should be that OPs should have
wild card certificates if they provide OpenID identifiers of the above
form. I question this recommendation.
Does the OpenID RP code operate correctly if a wild card certificate is
Isn't this to much of a burden to ask of OPs?
Wouldn't it be better for security if this connection used SSL/TLS?
