title: RabbitMQ 3.3.1 can not login with guest/guest
body: <p>I have installed the latest version of RabbitMQ on a VPS Debian Linux box. Tried to get login through guest/guest but returned with the message <strong>login failed</strong>. I did a little research and found that for security reason its prohibited to get login via guest/guest remotely.</p>
  
  <p>I also have tried enabling guest uses on this version to get logged in remotely by creating a <code>rabbitmq.config</code> file manually (because the installation didn't create one) and placing the following entry only</p>
  
  <pre><code>[{rabbit, [{loopback_users, []}]}].
  </code></pre>
  
  <p>after restart the rabbitmq with the following command. </p>
  
  <pre><code>invoke-rc.d rabbitmq-server stop -- to stop
  invoke-rc.d rabbitmq-server start -- to start
  </code></pre>
  
  <p>It still doesn't logged me in with guest/guest. I also have tried installing RabbitMQ on Windows VPS and tried to get log in via guest/guest through localhost but again i get the same message <strong>login failed</strong>.</p>
  
  <p>Also provide me a source where I could try installing the old version of RabbitMQ that does support logging remotely via guest/guest.</p>
