I have the following rules in my 2.6 config file: ----- external_acl_type AlmostNoInternetChecker %LOGIN /usr/local/squid/libexec/squid_ldap_group -R -b "dc=companyname,dc=local" -D "cn=Administrator,cn=Users,dc=companyname,dc=local" -w "mysecret" -f "(&(objectclass=person)(sAMAccountName=%v)(memberof=cn=%a,cn=AlmostNoInt ernet,cn=Domain Users,dc=companyname,dc=local))" -h 10.10.10.1 acl AlmostNoInternetAccess external AlmostNoInternetChecker AlmostNoInternet http_access deny all AlmostNoInternetAccess ----- I want to know if my external_acl_type spelling is good. My Active Directory setup: - companyname.local - Users - Computers - Domain Users - PersonA (user) - PersonB (user) - PersonC (user) - AlmostNoInternet (securitygroup - global) PersonA is a member of group AlmostNoInternet. Before the ldap group checking is done the user has done a good login. Regards, Jaap
