Hi Doug, Thanks for posting the instructions. We are trying to do the same thing and will try out your instructions. I do have 1 question about the instruction: You mentioned to bring in this dependency: implementation "org.apereo.cas:cas-server-support-saml-idp:${project.' cas.version'}"
But when I read CAS documentation: https://apereo.github.io/cas/6.3.x/integration/Configuring-SAML-SP-Integrations.html it mentions * cas-server-support-saml-sp-integrations *as the dependency. Do you know what's the difference between the two?
