I tried with this guide but it still not work. Have you ever tried this? http://kb.papercutsoftware.com/Main/ConfiguringSquidProxyToAuthenticateWithActiveDirectory

You still have to type the username/password at the prompt. You can save the username/password, but you are still prompted each time you start your browser.
