hello, i am trying Squid kerberos authentication instead of NTLM authentication due to resolve compatibility issue with latest version of windows. Only two things if i can: 1) in squid.conf, i have to specify windows user with the first capital letter. Ex: user = User@DOMAIN. If i specify user@DOMAIN i have no authentication to surf 2) squid/access.log, in some page, i see a DENIED request and then a TCP_MISS with the same page. It seems the browser try to access to a page and it is not authenticated by the proxy server. Then the client retries and can reach the page. Is it normal? Thank you! Francesco
