Hello. It seems delay pools don't work in my configuration. I use squid_ldap_auth to authenticate users in Active Directory: auth_param basic program /usr/local/libexec/squid/squid_ldap_auth \ -R -b "DC=test,DC=com" -D "unix@xxxxxxxx" -w xxx -f "sAMAccountName=%s" 1.1.1.1 and external_acl_type active_directory_group ttl=60 %LOGIN /usr/local/libexec/squid/squid_ldap_group \ -R -b "DC=test,DC=com" -D "unix@xxxxxxxx" -w xxx \ -f "(&(sAMAccountName=%u)(memberOf=CN=%g,OU=Proxy,OU=Internet Services,DC=test,DC=com))" 1.1.1.1 These are external ACLs for delay pools in config file: acl ad_speed_128k external active_directory_group speed_128k acl ad_speed_256k external active_directory_group speed_256k acl ad_speed_512k external active_directory_group speed_512k And to use different outgoing channels: acl ad_channel_1 external active_directory_group channel_1 acl ad_channel_2 external active_directory_group channel_2 acl ad_channel_3 external active_directory_group channel_3 http_access allow ad_channel_1 http_access allow ad_channel_2 http_access allow ad_channel_3 I've configured Squid to use different outgoing channel for different groups: tcp_outgoing_address 192.168.252.5 ad_channel_2 tcp_outgoing_address 192.168.252.9 ad_channel_3 And limit speed for other groups: delay_pools 3 delay_class 1 2 delay_class 2 2 delay_class 3 2 delay_access 1 allow ad_speed_128k delay_access 1 deny all delay_access 2 allow ad_speed_256k delay_access 2 deny all delay_access 3 allow ad_speed_512k delay_access 3 deny all delay_parameters 1 128000/128000 16000/16000 delay_parameters 2 256000/256000 32000/32000 delay_parameters 3 512000/512000 64000/64000 And when I add some user to speed_128k and channel_2 AD groups, he uses 2nd channel as expected, but delay pools don't apply to it. What is wrong? If required I can past whole my config. Thanks! -- Sergey
