Hello @ all! I´m Using Squid 2.7.STABLE7 on Ubuntu 10.04. I´ve managed to get ntlm_auth working with groups in th AD. I can browse simple pages, but when I open an https site, it gives me an 2nd login-window. I log in with my username of the AD, and browsing continues. But why do I get this login? My squid.conf: error_directory /usr/share/squid-langpack/de auth_param ntlm program /usr/bin/ntlm_auth = --helper-protocol=3Dsquid-2.5-ntlmssp auth_param ntlm children 30 auth_param ntlm max_challenge_reuses 0 auth_param ntlm max_challenge_lifetime 2 minutes # ntlm_auth from Samba 3 supports NTLM NEGOTIATE packet auth_param ntlm use_ntlm_negotiate on auth_param basic program /usr/bin/ntlm_auth = --helper-protocol=3Dsquid-2.5-basic auth_param basic children 5 auth_param basic realm Squid proxy-caching web server auth_param basic credentialsttl 2 hours external_acl_type testForNTGroup %LOGIN /usr/lib/squid/wbinfo_group.pl acl inGroupP external testForNTGroup BC_POWER_USER acl inGroupA external testForNTGroup BC_ADMIN_USER acl inGroupS external testForNTGroup BC_STANDARD_USER acl all src all acl manager proto cache_object acl localhost src 127.0.0.1/32 acl to_localhost dst 127.0.0.0/8 acl Allowed_Ports port 80 99 443 21 563 488 777 210 1025-65535 http_access allow inGroupA http_access allow inGroupS http_access allow inGroupP http_access deny !Allowed_Ports http_access deny all http_port 3128 hierarchy_stoplist cgi-bin ? access_log /var/log/squid/access.log squid refresh_pattern ^ftp: 1440 20% 10080 refresh_pattern ^gopher: 1440 0% 1440 refresh_pattern -i (/cgi-bin/|\?) 0 0% 0 refresh_pattern (Release|Package(.gz)*)$ 0 20% 2880 refresh_pattern . 0 20% 4320 acl shoutcast rep_header X-HTTP09-First-Line ^ICY.[0-9] upgrade_http0.9 deny shoutcast acl apache rep_header Server ^Apache broken_vary_encoding allow apache extension_methods REPORT MERGE MKACTIVITY CHECKOUT hosts_file /etc/hosts coredump_dir /var/spool/squid ---------------------------------------------------------------- FIBRO GmbH Weidachstraße 41-43 DE-74189 Weinsberg Registergericht Stuttgart, HRB 100248 USt-ID-Nr.
