Apache's HttpClient 4.0 does not provide support for the NTLM authentication scheme out of the box and probably never will. The reasons for that are legal rather than technical. (Source: http://hc.apache.org/httpcomponents-client/ntlm.html)

But Apache proposes an implementation blue print using the classes JCIFSEngine and NTLMSchemeFactory.

The last step is to glue it together. This example authenticates against IIS6 and Windows2003 domain.

 httpclient = new DefaultHttpClient();
 httpclient.getParams().setParameter("http.useragent", "Mozilla/5.0 (X11; U; Linux i686; en; rv:1.7.3)");
 httpclient.getAuthSchemes().register("ntlm", new NTLMSchemeFactory());
 httpclient.getCredentialsProvider().setCredentials(new AuthScope(HOSTNAME, -1),
                new NTCredentials(USERNAME, PASSWORD, LOCAL, DOMAIN));
