Hi, I instaled a Squid 2-5 Stable 13 working together Dansguardian and authenticating in Active Directory. The winbind is operational and the NTLM authentication are working as well . The problem is Basic authentication, the slot #1 are constantly in BUSY state and requests are increasing until restart or reload squid. I monitored that some "requests" were from a Cookie. squid.conf auth_param ntlm program /usr/bin/ntlm_auth --helper-protocol=squid-2.5-ntlmssp auth_param ntlm children 60 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 5 auth_param basic realm Informe a senha de rede para acesso a Internet auth_param basic credentialsttl 2 hours ******************************************************************************************************* smb.conf password server = server1 winbind uid = 10000-20000 winbind gid = 10000-20000 winbind enum users = yes winbind enum groups = yes realm = domain.com winbind use default domain = yes template shell = /bin/bash template homedir = /home/%D/%U Thanks for helpping.
