<p class="MsoNormal">Hi, attempting to integrate Shibboleth/SAML with SAS (Statistical Analysis Software). The SAS Servers and web server/SP are located inside Google Cloud (GCP) and the IdP is located outside of GCP LB.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Shibboleth version is 2.6.1 and it is running on Linux and apache 2.4.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We seem to have been able to get the initial logon to authenticate, but, once the post back to …/SAML2/POST occurs, it begins an infinite loop bouncing between a GET and POST to …SAML2/POST.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I am looking at the trace data in my browser, and the SAS logs, but, I can’t see where the problem is.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Can someone give me a pointer on where to look or what to look for to determine the cause of this behavior?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks in advance, Dennis<o:p></o:p></p>
