My server is allowing any and all access to the internet and I cannot figure out why.

I have set up the server to distribute IP's using DHCPD3. It allow addresses in the range of 192.168.46.100-192.168.46.251

Squid is set up as the proxy server to help increase bandwidth through caching. I want to use ncsa_auth to restrict access to users with username and passwords.

I thought I had it set up correctly, but authentication keeps being bypassed and access is still unrestricted.

here is the squid.conf

Any help would be nice. Thanks
