Thanks it seems to work!

Though a couple of comments:

The prompt, "You entered the server URL at the RP" confused me a
little. What is RP? Write the acronym out in full (or use the abbr tag
with a title) or why not use the terminology "consumer"?

Oh I think you might need to fix this too:
http://www.openidenabled.com/resources/openid-test/checkup/start?openid_url=http%3A%2F%2Fopenidenabled.com%2Fphp-openid%2Ftrunk%2Fexamples%2Fserver%2Fserver.php

Thanks again! :)
