Description

I'm trying to use the native Windows NTLM negotiation as described at http://svn.apache.org/repos/asf/httpcomponents/httpclient/trunk/httpclient-win/src/examples/org/apache/http/examples/client/win/ClientWinAuth.java
but I need to explicitly set a proxy.

if (!WinHttpClients.isWinAuthAvailable()) {
	System.out.println("Integrated Win auth is not supported!!!");
}

HttpClientBuilder httpClientBuilder = WinHttpClients.custom();

HttpHost httpProxy = new HttpHost("proxyserver.example.com", 3128);

httpClientBuilder.setProxy(httpProxy);
CloseableHttpClient httpclient = httpClientBuilder.build();

try {
	HttpGet httpget = new HttpGet("http://www.google.it");

	System.out.println("Executing request " + httpget.getRequestLine());
	CloseableHttpResponse response = httpclient.execute(httpget);
	try {
		System.out.println("----------------------------------------");
		System.out.println(response.getStatusLine());
		EntityUtils.consume(response.getEntity());
	} finally {
		response.close();
	}
} finally {
	httpclient.close();
}

The response contains the following line

HTTP/1.0 407 Proxy Authentication Required

In the attachments both the source code above and the complete log of the negotiation (I obviously changed the real proxy).

What's wrong?
