Hello, I am using squid 5.9 with AD Kerberos authentication and could not solve the problem of sending incorrect request according to client configuration followed by the correct one, i.e.: 1695983264.808 0 x.y.z TCP_DENIED/407 4135 CONNECT th.bing.com:443 - HIER_NONE/- text/html 1695983264.834 21 x.y.z TCP_TUNNEL/200 6080 CONNECT th.bing.com:443 name@domain FIRSTUP_PARENT/squid-parent - There are some web servers which are not working even when the correct request follows afterwards. Anyone experienced this behavior? Any specific settings of Windows clients? Thank you very much.
