how can this be the same problem? It's very different problem.

when talking about "transparent" proxy, you apparently mean "intercepting"
proxy - client tries to connect to a server, but the connection is
redirected to proxy.

Now, the client can _not_ log onto a proxy, if it believes it connects to
the server, not to the proxy - it does not know there's a proxy.

You must configure proxy (explicitly, or using WPAD protocol) if you want
your clients to authenticate on them.

Or, you must use out-of-band authentication protocol (external program that
will check who is the client, e.g. who is logged on the client computer.
