This is an <a href="http://www.openid.net/">OpenID</a> server
endpoint. This server is built on the <a
href="http://github.com/openid/php-openid">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.
