title: How to allow slaves to connect to jenkins master without "-secret" jnlp option?
body: <p>Yesterday, my jenkins master (v 1.646, linux debian Jessie 8.3) was working and several slaves was connecting on it via the jnlp command:</p>
  
  <pre><code>java -jar slave.jar -jnlpUrl http://myhost:8080/computer/bob-pc.local/slave-agent.jnlp
  </code></pre>
  
  <p>Now I guess something changed (war update ? plugin update ? security option changed ?) because now my slaves cant connect anymore since the jnlp command is now :</p>
  
  <pre><code>java -jar slave.jar -jnlpUrl http://myhost:8080/computer/bob-pc.local/slave-agent.jnlp -secret rt435te435a208c7201d99f7b1e5dd9c044da86d12efd8527
  </code></pre>
  
  <p>The <code>-secret ...</code> part of the command is new and I cant figure out which change added this option.</p>
