title: Gerrit push to refs/for/master prohibited
body: <p>I have updated the <em>All Project</em> access permission yesterday, people says that they cannot push changes to repository this morning. After I recovered the access permission, they still cannot push changes to repository, only <code>clone</code> works fine. While push changes to remote repository, it says that:</p>
  
  <pre><code>![remote rejected] HEAD -&gt; refs/for/master (prohibited by Gerrit)
  </code></pre>
  
  <p>All our other projects are inherit from <em>All project</em>'s access permission, I updated the access permission to the lowest level (i.e. <em>Anonymous</em> can push branch to <code>refs/heads/*</code>) for test, but I find that the <em>Administrator</em> cannot push changes to the repository too! </p>
  
  <p>Is there any other settings need to add?</p>
