Issue/Introduction

I'm trying to configure SAML in the lab. I need to create a firewall request to open paths to the correct hosts. My question regards the path from the SP to the IdP. Does the request to the IdP from the SP go back through the load-balancer or does it take a direct path?.

Environment

Release : 21.2

Resolution

Based on the following documentation the communication to the IDP will not go back through the load balancer.
