First of all, NTLM and Negotiate authentication requires client-side
persistent connections so make sure they are enabled in your tests.  See
Agent::pconn_use_lmt and related options for PGL knobs [1].

As for the error, it means that the proxy requested authentication (407
status code), but did not sent a Proxy-Authenticate header.  You can see
that in the proxy reply headers dump above.  It may happen because
persistent connections are not enabled.  So I suggest you to fix that
first.  If it does not help, you need to look at the proxy
configuration.

Regards,
  Dmitry
