SAML message delivered with POST to incorrect server URL. with Google Cloud Load Balancer

[O'Quinn, Dennis]

Thank you Scott, impressed with the quick turnaround...

RE: the ServerName, I was asking because that 'name' is defined all throughout SAS and it has been a *bear* getting the configuration right just for SAS relative to the LB (where the GCP 'external' name (sascloud) and port (443) has to be defined in some places and the GCP 'internal' name/port (<sashostname>/8343) has to be defined in others (many places in both cases).  Since SAS is hosting its own web server, I wasn't comfortable changing that setting (currently the internal name/port) for fear it would break SAS....

So, since we will have to use the 'external' name/port, I will give that a try and see if it still works...

If it will help you and the community, I will post back what I did when I get it working.

Thanks much, D

Apache requires that be set for most  applications to run properly in an environment like that, so yes, that's the only way for Shibboleth to work since it has to be set regardless. That's a feature (you configure your web server properly and the SP just works). IIS doesn't support virtualization so the SP is forced to compensate, but Apache does so there's no reason to do anything special.

If your application functions without ServerName set, it either never generates self-referential links or it's got a bug.
