Hi Marcus and all. It turned out that I just needed a restart of the proxy server. I read on a post who was having the same problem and a restart worked for him. I tried that and all worked for me too. Kerberos auth is not working as expected. I only had to follow the wiki example line by line. Thank you very much.
