Hi, I can not for the life of me work out how to use ext_kerberos_ldap_group_acl with squid 3.2.6 I have authentication with negotiate_kerberos_auth working fine but I also want authorisation helper for group membership. Relevant squid.conf config below.. # Kerberos Auth auth_param negotiate program /usr/lib64/squid/negotiate_kerberos_auth auth_param negotiate children 40 auth_param negotiate keep_alive on # Group ACL Helper external_acl_type ldap_group ttl=60 negative_ttl=60 %LOGIN /usr/lib64/squid/ext_kerberos_ldap_group_acl -d -g ALL@ -D my.internal What is the ALL@ for ? Does someone have a working config against Windows 2008 AD/LDAP ? To be honest, at the moment I am using this external helper ext_wbinfo_group_acl which is working fine.. external_acl_type ldap_group ttl=300 children-max=50 children-startup=40 %LOGIN /usr/lib64/squid/ext_wbinfo_group_acl -K .. but is ext_kerberos_ldap_group_acl better or should I leave authorisation up to ext_wbinfo_group_acl since I have it working? Is either better than the other?
