Some update, I have look into some other organizations SAML2 metadata (which is also registered to the Identity Federation we want to join), and basically nobody brother adding the "urn:oasis:names:tc:SAML:2.0:nameid-format:persistent" entry despite the requirement.
So in this case, I would also follows them, and don't brother adding the " urn:oasis:names:tc:SAML:2.0:nameid-format:persistent" then... I am still curios for the above question, if anybody have more info I will also want to learn more :D Cheers! - Andy -- - Website: https://apereo.github.io/cas - Gitter Chatroom: https://gitter.im/apereo/cas - List Guidelines: https://goo.gl/1VRrw7 - Contributions: https://goo.gl/mh7qDG --- You received this message because you are subscribed to the Google Groups "CAS Community" group.
