title: Bad configuration option in GIT (AllowUsers)
body: <p>I'm trying to clone a project by using ssh from the gitlab repository, but the problem is that I can't do it because message <code>Permission denied: (publickey)</code>. </p>
  
  <p>I have generated ssh key and added to my gitlab account, but it didn't worked out. Now I'm trying to add a config file into my ssh folder, which looks like this:</p>
  
  <pre><code>Host gitlab.com
      User user
      Hostname gitlab.com
      IdentityFile ~/.ssh/id_rsa
      TCPKeepAlive yes
      IdentitiesOnly yes
      AllowUsers user
  </code></pre>
  
  <p>But the GIT says: <code>Bad configuration option: allowusers</code>.</p>
  
  <p>Could someone explain me why?</p>
