This is an <a href="http://www.openid.net/">OpenID</a> server
endpoint. This server is built on the <a
href="http://www.openidenabled.com/openid/libraries/php">JanRain PHP OpenID
library</a>. Since OpenID consumer sites will need to directly contact this
server, it must be accessible over the Internet (not behind a firewall).
</p>
<p>
To use this server, you will have to set up a URL to use as an identifier.
Insert the following markup into the <code><head></code> of the HTML
document at that URL:
</p>
<pre><link rel="openid.server" href="%s" /></pre>
<p>
Then configure this server so that you can log in with that URL. Once you
have configured the server, and marked up your identity URL, you can verify
that it is working by using the <a href="http://www.openidenabled.com/"
>openidenabled.com</a>
<a href="http://www.openidenabled.com/resources/openid-test/checkup">OpenID
Checkup tool</a>:
<form method="post"
action="http://www.openidenabled.com/resources/openid-test/checkup/start">
<label for="checkup">OpenID URL:
</label><input id="checkup" type="text" name="openid_url" />
