<p class="MsoNormal"><span lang="EN-US">Is this usable in a situation where a “personal” IdP is used on a local machine, which uses an X.509 certificate signed by a single root certificate? This means many “dynamic” IdP certificates from the point of view of
the SP, as there will be many such “personal” IdPs, all of which must be trusted by the SP.<o:p></o:p></span></p>
