Hi all, I have configured SQUID as HTTP proxy and allowed some range of IPs. And when I use internet form my PC for which I have configured this SQUID PC as proxy server and i can see all the traffic going through the proxy. Now I want to allow the PC's to access the Proxy server only if the login credentials authentication is success. And if the PC's fail to authenticate then the proxy should block the traffic. I have modified the /etc/squid/squid.conf file but looks like it needs a external auth server like LDAP, APACHE & etc... Let me know what needs to be done to achieve this. Thanks & regards -Pavan
