See the protocol documentation on the CAS website: https://apereo.github.io/cas/6.0.x/protocol/CAS-Protocol.html
You'll note that the big change between 2 and 3 on the server side is that there are different service validation end points. Protocol v3 works just fine for modern libraries, and will get you your attributes. So yes, a single server can support the two versions, it is up to the client to choose what it wants to call, and it needs to hit the correct validation URL. You can additionally add support for more protocols, as you can see in the documentation.

I just realized that CAS 2 doesn't support the attribute rerteriveing, response only contains principle with user name and proxy information. Thanks for any help. -- - 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.
