Hi to all! I've a 'little' problem.... I've followed the instruction of this guide: http://wiki.squid-cache.org/ConfigExamples/Authenticate/WindowsActiveDirectory And i've setup successfully the ntlm and basic authentication. browser and application works well, most of them use ntlm... But now i've a throuble with kerberos auth, as one win7 client seem to use kerberos instead of ntlm. I get the following error on cache.log 2014/10/03 17:05:35| negotiate_wrapper: Got '...cut...' from squid (length: 219). 2014/10/03 17:05:35| negotiate_wrapper: Decode '...cut...'
