Hi, It is possible to decode those "negotiate_kerberos_auth" debug messages? I tried "base64 -d", but it shows a lot of garbage and almost nothing readable. Ex: negotiate_kerberos_auth.cc(315): pid=32562 :2013/10/30 13:32:45| negotiate_kerberos_auth: DEBUG: Got 'YR YIIF0w/very/big/code/here/0z3Q==' from squid (length: 1999). echo "YIIF0w/very/big/code/here/0z3Q==" |base64 -d ßÛ¦Lbc¡JE¦µãS¹¾7Å5ôõúÒ bÖïºaÐó0æ3Rq¤è and a lot of these things
