In my squid.conf, i am trying to grant access ONLY to a set of predefined sites for a group of users (those who are member of limitedsurfers). They are not allowed to access any other thing from the Internet. The following is the acl which i created All my other rules are working perfectly... Squid Version: 2.6 Stable OS: CentOS 5.2 First from authentication rule; auth_param basic program /usr/lib/squid/pam_auth external_acl_type unix_group %LOGIN /usr/lib/squid/squid_unix_group acl limited_surfers_acl external unix_group limitedsurfers Then the particular acl; acl limited_sites dstdomain "/etc/squid/include-files/limited_site.squid" http_access allow limited_surfers_acl limited_sites http_access deny limited_surfers_acl deny_info ERR_LIMITED_SURFERS limited_surfers_acl Now the situation is; It is perfectly granting access to the sited listed in the limited_site.squid file But when i try to access some other site, it will ask the username/password for 3 times (even when we give the correct username/pass) then only it is denying the request. Why it is happening so? I have almost the same kind of rule like this for a particular list of IP's instead of users. That is working perfect for allowing and denying. Can anybody help me in this case...
