I assume you mean you want to see what happens when invalid credentials
are sent. To do that, you have the client send invalid credentials to
the proxy.

In HTTP authentication credentials have to be re-sent on every request.
So simply sending a request with invalid/incorrect ones is enough to
trigger the 407 message at any time you want.

Note: NTLM authentication does not obey the rules for HTTP
authentication. You also have to disable persistent client connections
to do this particular test. That is not a good thing to do in production
though, so the test is not a useful behaviour test.

Please upgrade if you can. That software is all over 5 years old.
