[jira] [Commented] (HTTPCLIENT-1598) Native Windows Negotiate/NTLM
via JNA + 407 Proxy Authentication Required
[ https://issues.apache.org/jira/browse/HTTPCLIENT-1598?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14277689#comment-14277689 ]
Michael Osipov commented on HTTPCLIENT-1598:
--------------------------------------------
Ciao Giacomo,
I haven't yet looked at the files but the entire SSPI/JNA is experimental and is incomplete. I have already done a code analysis and promised to work on that mid-term but working right now at 150 % :-(
Meanwhile, can you reproduce the issue with {{curl}}? The available binary for Windows uses the same API, namely SSPI and I have contributed some effort to make that run smoothly.
I'd like to know whether this is caused by the problematic code I have found in the SSPI block or your setup.
Invoke curl with:
{noformat}
> curl --verbose -U : --proxy-negotiate -x http://<host>:<port> <url>
{noformat}

> Project: HttpComponents HttpClient
> Issue Type: Bug
> Components: HttpAuth
> Affects Versions: 4.4 Beta1
> Environment: Windows 8
> Reporter: Giacomo Boccardo
> Labels: 407, jna, native, ntlm

> 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.
> {code:java}
> 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();
> }
> {code}
> 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?
