Hello, I want to implement user authentication (kerberos) on an already existing proxysystem without user authenticaion. But I know that there are clients, which can't do any authentication. So is it possible to configure squid, that it ask for proxy authentication credentials, but if the client can't authenticate skip this acl and go on with the next acls ? I tried something like this, but without success: --snip-- # kerberos authentication auth_param negotiate program /usr/sbin/negotiate_kerberos_auth -s HTTP/www-proxy.mydomain -k /etc/squid/HTTP.keytab auth_param negotiate children 10 auth_param negotiate keep_alive on acl kerberosauth proxy_auth REQUIRED acl noauth_port localport 8880 acl give_access any-of kerberosauth noauth_port http_access allow give_access --snip-- -- Regards Dieter -- I do not get viruses because I do not use MS software.
