Hi guys. I hope someone can cast a light in my problem here. I'm using squid-2.5STABLE4 on Mandrake 10. I'm using winbind authentication and it works fine. But I trying to use external_acl_type too, but not working. Always I got Access Denied, even when the script returns OK (at least I got "OK" in console). Please, someone can see anything wrong here: thank you in advance.
