Answer 1

I have same problem. I want to use android asynk http, but i not found ntlm auth I found solution: 1)use above answer,download and import jcifs-1.3.17.jar 2)then i download https://github.com/loopj/android-async-http (not JAR file) and import in my project, 3) then in file AsynkHttpClient.java after

  httpClient = new DefaultHttpClient(cm, httpParams);

insert

 httpClient.getAuthSchemes().register("ntlm", new NTLMSchemeFactory());
    httpClient.getCredentialsProvider().setCredentials(
            // Limit the credentials only to the specified domain and port
            new AuthScope(AuthScope.ANY_HOST, AuthScope.ANY_PORT),
            // Specify credentials, most of the time only user/pass is needed
           new NTCredentials("username", "pass","", "")


    );

!!!!!!! then very important you must comment like this

 httpClient.addRequestInterceptor(new HttpRequestInterceptor() {
            @Override
            public void process(final HttpRequest request, final HttpContext context) throws HttpException, IOException {
                AuthState authState = (AuthState) context.getAttribute(ClientContext.TARGET_AUTH_STATE);
                CredentialsProvider credsProvider = (CredentialsProvider) context.getAttribute(
                        ClientContext.CREDS_PROVIDER);
                HttpHost targetHost = (HttpHost) context.getAttribute(ExecutionContext.HTTP_TARGET_HOST);

//                if (authState.getAuthScheme() == null) {
//                    AuthScope authScope = new AuthScope(targetHost.getHostName(), targetHost.getPort());
//                    Credentials creds = credsProvider.getCredentials(authScope);
//                    if (creds != null) {
//                        authState.setAuthScheme(new BasicScheme());
//                        authState.setCredentials(creds);
//                    }
//                }
            }
        }, 0);

that all you need :)

here is the full fledged working for this.

try
  {
     DefaultHttpClient httpclient = new DefaultHttpClient();

  // register ntlm auth scheme
     httpclient.getAuthSchemes().register("ntlm", new NTLMSchemeFactory());

     httpclient.getCredentialsProvider().setCredentials(
             new AuthScope(AuthScope.ANY_HOST, AuthScope.ANY_PORT),
             new NTCredentials("username","password"));

             //xx = ip address yy = port
     HttpPost httpPost = new HttpPost("http://xx.xx.xx.xx:yy/");

     Log.e(TAG, "executing request" + httpPost.getRequestLine());
     HttpResponse response = httpclient.execute(httpPost);

     HttpEntity entity = response.getEntity();

     Log.e(TAG, "" + response.getStatusLine());
     if (entity != null)
     {
        Log.e(TAG, "Response content length: " + entity.getContentLength());
     }
     if (entity != null)
     {
        Log.e(TAG, "Response stream: " + getMessage(entity.getContent()));
        entity.consumeContent();
     }

  }
  catch (Exception e)
  {
     Log.e(TAG, "" + e.getMessage());
  }

please note to include these imports only

import java.net.HttpURLConnection;
import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.auth.AuthScope;
import org.apache.http.auth.NTCredentials;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.impl.auth.NTLMSchemeFactory;
import org.apache.http.impl.client.DefaultHttpClient;

and do use httpclient-android-4.3.5.1.jar only.

Answer 3

Looks to me that you are possibly behind a proxy? NTLM looks to be a largely undocumented Microsoft protocol:

You cannot simply use Basic Auth because this is some different authentication scheme required by the server to whom you are speaking, or by a proxy in between you and your destination.

Answer 4

here is the answer through code:

add below code to your android file

            DefaultHttpClient httpclient = new DefaultHttpClient();
            // register ntlm auth scheme
            httpclient.getAuthSchemes().register("ntlm", new NTLMSchemeFactory());
            httpclient.getCredentialsProvider().setCredentials(
                    // Limit the credentials only to the specified domain and port
                    new AuthScope(AuthScope.ANY_HOST, AuthScope.ANY_PORT),
                    // Specify credentials, most of the time only user/pass is needed
                    new NTCredentials(username, password, "", "")
            );

            HttpUriRequest httpget = new HttpGet(your_URL);
            HttpResponse response = httpclient.execute(httpget);
            String responseBody = EntityUtils.toString(response.getEntity());
            Log.i(tag,"responseBody =>>>>>>>>>>"+responseBody);

now download lib and java file from

https://github.com/masconsult/android-ntlm

and copy jcifs-1.3.17.jar to your lib folder and JCIFSEngine and NTLMSchemeFactory to your package. (you can change package if you want..)

Thats it your app is ready to run.
