Active Directory authentication using Spring and Apache Library

Recently, I started to work AD authentication again and this is little snippet of AD authentication portion.

Create simple springboot and tested with it.

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

import java.io.IOException;
import java.io.UnsupportedEncodingException;
import java.util.Arrays;

@SpringBootApplication
public class AdAuthenticationApplication {

/*    public static void main(String[] args) {
      SpringApplication.run(AdAuthenticationApplication.class, args);
      }
      */
    public static void main(String[] args){

      CredentialsProvider credsProvider = new BasicCredentialsProvider();
      credsProvider.setCredentials(AuthScope.ANY,
              new NTCredentials("username", "password", "", "domain"));
      
      RequestConfig config = RequestConfig.custom().setTargetPreferredAuthSchemes(Arrays.asList(AuthSchemes.NTLM)).build();

      CloseableHttpClient httpclient = HttpClients.custom().setDefaultRequestConfig(config).build();


      HttpHost target = new HttpHost("web_url", 80, "http");

      // Make sure the same context is used to execute logically related requests
      HttpClientContext context = HttpClientContext.create();
         context.setCredentialsProvider(credsProvider);

      // Execute a cheap method first. This will trigger NTLM authentication
      HttpGet httpget = new HttpGet("url_path_without_FQDN(ex) /home.aspx)");
      CloseableHttpResponse response1 = null;
            try {
                  response1 = httpclient.execute(target, httpget, context);
            } catch (ClientProtocolException e) {
                  // TODO Auto-generated catch block
                  e.printStackTrace();
            } catch (IOException e) {
                  // TODO Auto-generated catch block
                  e.printStackTrace();
            }
      try {
          HttpEntity entity1 = response1.getEntity();
      } finally {
          try {
                        response1.close();
                  } catch (IOException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                  }
      }
}
