title: Configuring public key of users via gitolite throws error
body: <p>I have added the public key of a user and pushed to the server.<br>
  But while running the <code>gl-setup</code> I have used like <code>/tmp/id_rsa.pub</code> instead of <code>/tmp/rekha.pub</code>.</p>
  
  <p>Now I have altered the file name and then again tried to run the <code>gl-setup</code>.</p>
  
  <p>It shows the message at last like this</p>
  
  <pre><code>rekha.pub maps to user id_rsa, not rekha.
  You will not be able to access gitolite with this key.
  Look for the 'ssh troubleshooting' link in http://sitaramc.github.com/gitolite/.
  </code></pre>
  
  <p>How to solve this problem?</p>
