title: git push origin DENIED by fallthru, hook declined: gitolite
body: <p>I am having a problem pushing with <code>git</code> using Gitolite.<br>
  When I try this: </p>
  
  <pre><code>git push origin :refs/tags/deployment
  </code></pre>
  
  <p>I get this error: </p>
  
  <pre><code>remote: D NAME/install.py repos michael DENIED by fallthru
  remote: error: hook declined to update refs/tags/deployment
  To gitolite@admin:repos
   ! [remote rejected] deployment (hook declined)
  error: failed to push some refs to 'gitolite@admin:repos'
  </code></pre>
  
  <p>I have given the group <strong><code>deploy</code></strong> [of which the user <strong><code>michael</code></strong> is a member of] permission to delete branches in the Gitolite config: </p>
  
  <pre><code>@deply  =   michael
  
  repo  repos
  
          RWD    =   @deply
  </code></pre>
  
  <p>I have seen this post: "<a href="https://stackoverflow.com/questions/9121005/unable-to-push-in-git-why">Unable to push in Git. Why?</a>"</p>
  
  <p>But I am not using any hooks that I am aware of and cannot find anything thing else that might relate. </p>
  
  <p>Is there something im missing perhaps?<br>
  Has anybody come across this?</p>
