<p><strong>Is it possible to use <code>OpenID</code> for <em>both</em> <code>.NET</code> web sites and <code>PHP</code> websites (Apache/Linux)?</strong>  </p>

<p>I have a manager that wants <em>single sign-on for access to any/all web sites, regardless of which web server hosts a web site</em>.  </p>

<p>I create <code>.NET</code> web apps and the <code>PHP</code> web sites/apps are done by another programmer.  </p>

<p>How would I go about using <code>OpenID</code> for a <code>.NET</code> web app?  </p>

<p>What about for the <code>PHP</code> programmer?</p>
