We have a public-facing app which uses the SAML Sign-in authentication scheme. We need this because we integrate with a third-party application and it uses SAML for authentication.
We have everything set up between IAM and APEX and it works but we are redirected to the Oracle IAM Login page instead of our application's login page, even though we select 'Go To: Login Page' in the 'Session Not Valid' section of the authentication scheme configuration. We've tried custom code as well as calling 'apex_authentication.is_authenticated' in the 'Verify Function Name' field.

Does anyone have any experience setting this up successfullY? Looking for someone to point us in the right direction. Or, provide a working example if you have one. We have logged a support ticket but they haven't been any help so far.
Thanks,
