[keycloak-user] Does keycloak tomcat adapter require IDP metadata.xml ??

Hello, I have installed the keycloak tomcat adapter in my tomcat 8 instance. I want to use ADFS as my IDP (no keycloak server) QUESTION: 1.) I configured the keycloak-saml.xml to point to the ADFS IDP. But I am surprised that there is no reference to the IDP metadata.xml file that I received from my ADFS admin? Is it used at all? How? Ken
