I just did :) the problem was the keytab, i created using linux command "net ads keytab create", i tested both linux ssh client and putty (PuTTY-0.58-GSSAPI-2005-07-24, i tested with another patched putty client, worked, but it didnt created/forwared my ticket) and all worked fine. Is "Kerberos for Windows" necessary for Windows/Putty? Thank you all for help.
