Hi all. I have a strange authentication issue in my squid 3.5.19. My workstations only can authenticate if they are entered into the domain. When they doesn't entered into the domain, I access any URL on browser (Firefox and Chrome tested) and I'm not able authenticate on the boxes that are shown to me. Squid logs show me "TCP_DENIED/407". Bellow is my squid.conf authentication configuration: --- auth_param ntlm program /usr/bin/ntlm_auth --helper-protocol=squid-2.5-ntlmssp auth_param ntlm children 140 auth_param ntlm keep_alive on auth_param basic program /usr/bin/ntlm_auth --helper-protocol=squid-2.5-basic auth_param basic children 60 auth_param basic credentialsttl 10 hours auth_param basic realm enter your password acl authenticated proxy_auth REQUIRED http_access deny !authenticated --- I noticed that in Firefox's private tabs works perfectly. Am I doing something wrong? Has anyone experienced this?
