</span>Okay, well, regardless of how you do metadata aggregation, you're<br>
going to have to deal with that problem. Do you recognize the first<br>
occurrence or the last occurrence of any given IdP? I believe the SP<br>
can implement either of those policies.<br></blockquote><div><br></div><div>If I am not mistaken the SP by default uses first occurrence.

</span>The SP has very sophisticated metadata aggregation capabilities but I<br>
think you'll need a standalone metadata aggregator to do what you<br>
want. There is the Shibboleth Metadata Aggregator and there is pyFF<br>
(<a href="http://pyff.io" target="_blank">pyff.io</a>). Your mileage may vary.<br></blockquote><div><br></div><div>Thanks for the tip. I'll check it out</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
