Hello All, I have configured squid-2.6.STABLE.13 + NTLM authentication using basic scheme. But we get the "TCP_DENIED/407" error message in access log file The portion of squid configuration file is given below auth_param basic program /usr/local/squid26s13-NTLM/libexec/ntlm_auth -d \\Domain auth_param basic children 5 auth_param basic realm Squid proxy-caching web server auth_param basic credentialsttl 5 hours acl ntlm_users proxy_auth REQUIRED http_access allow ntlm_users http_access deny all Can ntlm_auth auth helper be used for basic scheme or should only be used with ntlm scheme? How to configure the NTLM authentication using basic scheme? Is there anyother helper available for ntlm authentication under basic scheme? I tried the helper in the commandline and get the following message #/usr/local/squid26s13-NTLM/libexec/ntlm_auth -d \\Domain ntlm_auth[7404](ntlm_auth.c:187): Adding domain-controller \Domain ntlm_auth[7404](ntlm_auth.c:460): options processed OK jas jas123 ntlm_auth[7404](ntlm_auth.c:284): managing request ntlm_auth[7404](ntlm_auth.c:290): ntlm authenticator. Got 'jas jas123' from Squid ntlm_auth[7404](ntlm_auth.c:440): sending 'BH Helper detected protocol error' to squid BH Helper detected protocol error Thanks, -Jegadeesh
