I'm going to assume that you are not managing and not running OS X Server here. While it's possible to set up a proxy server with OS X Server (with some added configuration work), your question seems to be specific to a client web browser configuration.
Privoxy is a web proxy tool that's available not only for Mac. In order to use the WikiLeaks public submission system as detailed above you can download the Tor Browser Bundle, which is a Firefox-like browser available for Windows, Mac OS X and GNU/Linux and pre-configured to connect using the anonymising system Tor. My browser and other applications are using the system proxy settings, in which I have saved my username and password for authenticating with the proxy. This is working fine. There is a persistent problem with system services that try to access information on the internet and don't see to have access to the proxy credentials in my user account. Logically enough, there is no need to enable proxy in Mac OS network preferences. First one is easy, go to Settings - Wi-Fi - Click on the blue circled i on your current network - Configure Proxy - Manual: Then open this URL ( sslca.io) in browser on your iPhone and install Proxie’s certificate. EnCee is a proxy tool for Notification Center (Mountain Lion). Adds Applescript, Automator, and command-line (Bash) support for Notification Center, working as a menu extra (status item). Main features: - Prowl support.
With an OS X client request from a web browser such as Safari or Firefox, the HTTP 407 Proxy Authentication Required messages usually indicate something that's been implemented by the local site administration or local network management. This can be a way to cache web content and also as a way to track and/or to restrict access to specific web sites.

If you're on your own network here (and not using OS X Server or some other web proxy), then this might be something weird with some local nanny filter installed in your gateway, or with some ISP web proxy outside your local network — more details on your network would be useful here.
