<p class="MsoNormal">Hello, <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’m working on having my Shibboleth IdP v4.0.1 absolve to another IdP (let’s call it IdP-NEW) for authentication. Therefore any applications/sites using my Shib-IdP for authentication will now absolve to IdP-NEW for authentication.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I followed this document on how to do this: <a href="https://shibboleth.atlassian.net/wiki/spaces/KB/pages/1459979597/Using+SAML+Proxying+to+another+IdP">
https://shibboleth.atlassian.net/wiki/spaces/KB/pages/1459979597/Using+SAML+Proxying+to+another+IdP</a><o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Some good progress was made but I hit a wall. When IdP-NEW hands the attributes off to Shib-IdP it appears to get stuck here. It’s not taking these.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The workflow that works: You go to the URL for the Shibboleth IdP enabled application that then redirects to IdP-NEW IdP for login. Once authentication there happens with the attributes set in the IdP-NEW relying party, we see that being
passed back over to Shibboleth IdP. Shibboleth IdP doesn’t appear to be translating or sending those attributes it got from IdP-NEW along over to the application.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I tried doing some additional testing and looking at different documents and haven’t been able to find what is missing. What needs to be done to have the Shib-IdP to accept that attributes from IdP-NEW and then pass those along to the application
to complete authentication? <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Here are the changes I made to configure and enable it, please let me know what I am missing:
