title: Support multiple login at the same time in OpenFire server
body: <p>I've configured OpenFire for using as server for my customers.</p>
  
  <p>But in following case, OpenFire doesn't give proper response:</p>
  
  <p><strong>Customer A</strong> login from two chat client connected to my server and chat with another <strong>Customer B</strong>.
  The problem is that, last active <strong>Customer A</strong> can only get Message from <strong>Customer B</strong> instead of getting message in both the chat client.</p>
  
  <p>Anyone have configured the OpenFire can suggest me the settings need to be changed.</p>
  
  <p>Thanks.</p>
