Using Upstream Proxy Authentication
We currently use Dansguardian with squid for our content filter. I have setup pfsense to be a captive portal on our guest network vlan and guest wireless network. Currently I am using the proxy server to forward to an upstream proxy. This works but it required that I enter a username/password or our proxy. What I would like is that instead of entering a username/password into the proxy config in pfsense is that it would instead prompt the users for a username and password.
Then we would be able to use our current proxy server authentication which has different groups and filters users based on which group they are in. Is this possible?
