Hi, I´ve getting trouble with Squid 2.6 in my company. The directors are cosidering to change it for a Blue Coat proxy. All the 60 NTLM Helpers are constantly in RESERVED or DEFERRED state. We are using ADS with security option, auth_param ntlm max_challenge_reuses 100 auth_param ntlm max_challenge_lifetime 20 minutes auth_param ntlm use_ntlm_negotiate on auth_param basic program /usr/bin/ntlm_auth --helper-protocol=squid-2.5-basic #auth_param basic program /usr/bin/ntlm_auth --debug-level=10 --helper-protocol=squid-2.5-basic --nt-response auth_param basic children 0 auth_param basic realm Informe a senha de rede para acesso a Internet auth_param basic credentialsttl 2 hours I think that problem is related with Basic authentication becouse when I set it off the "hang on" stoped. I hoped that Squid open source could solve our problems but unfortunately I never got support on the lists and the community. So I´m afraid that Free Software are gone away in my company.
