title: wildfly docker image authentication issue
body: <p>I've followed the instructions on the following link: <a href="https://registry.hub.docker.com/u/jboss/wildfly/" rel="nofollow">WildFly Docker image</a> in the section <strong>Extending the image</strong></p>
  
  <p>However, after I make the build, when I go to the URL <a href="http://localhost:9990" rel="nofollow">http://localhost:9990</a>, I have the following message:</p>
  
  <pre><code>The management interface could not be loaded.
  
  Authentication required.
  </code></pre>
