Http Negotiate unsupported ?

I'm following the exercise presented here:

http://java.sun.com/javase/6/docs/technotes/guides/security/jgss/lab/part6.html

IIS says it can accept Negotiate or kerberos.

The application RunHttpSpnego fails with exception saying it received a response code 401 from the server.

If I configure IIS to accept Negotiate,NTLM the application works correctly failing back to ntlm.

Unfortunately I would like a stronger authentication than ntlm

Any suggestion ?

Thanks
