Re: [squid-users] Forwarding request to upstream auth and proxy server

For this you probably need to configure Squid to provide a hardcoded
username+password in the cache_peer directive. See the login=...
cache_peer option.

If both proxies uses the same user database then Squid-2.5 can be
configured to "transparently" forward the proxy authentication to the
parent.

HTTP only supports one set of proxy user credentials per request. The user
cannot get two login questions.

I want to be able to authenticate locally via smb_auth against our W2k domain controllers and then forward the request to our upstream proxy server where the users need to be authenticated again. I have tried all manners of different config as I think it has something to do with the "always_direct", "never_direct" rules but just playing with these gets me confused.
