Answer 1

Your Kerberos configuration might be completely fine. The 401 messsage means that the authentication itself probably went fine. However, i suspect the webapp only allows users if they are assigned a Role. The SPNego mechanism does not assign such role out-of-the-box. You still need to configure a Realm that performs the mapping.

Answer 2

What library do you use on the server side? Did you enable debug flags to see what happens when the server processes the service ticket?
