<p class="MsoNormal"><span style="font-size:11.0pt">As an SP, we allow our customers to tell us that they are using Shibboleth for authentication, at which time they provide us with the EntityID of their IdP. Currently, our support staff validate their configuration
– in particular, confirming that the EntityID in (at least) one of the federation metadata aggregates that we use.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">We are now building a “Self Service” portal that would, among other things, allow them to set up their Shibboleth configuration themselves. We would like to be able to programmatically verify that the EntityID
they give us is one that we can use (i.e., that it maps to an IdP in federation metadata.) We could clearly do this by reading the federation metadata into an independent service and then checking that there is an IdP entry with that EntityId, but I’m not
happy about the duplication of effort that would take. <o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">So, my question: Is there an API on shibd (currently 3.0.4) that we could use for this purpose?<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">I guess we could construct a /Shibboleth.sso/Login URL with the entity ID. If it gets forwarded, then the entity ID is valid, and if we get an error, it’s not.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">Is there a more elegant way of doing this?<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
