Hello, I have problems with the authentication. I've followed the faq's rules: 1.Acl: acl foo proxy_auth REQUIRED http_access allow foo 2. External authenticator program. % cd helpers/basic_auth/NCSA % make % make install 3. Password file 4. Configure the external authenticator in squid.conf. For ncsa_auth you need to give the pathname to the executable and the password file as an argument. For example: auth_param basic program /usr/local/squid/libexec/ncsa_auth /usr/local/squid/etc/passwd But I'm not able to start Squid: /var/messages: Bungled squid.conf line 444: acl prueba proxy_auth REQUIRED Thanks!
