title: gitlab push via ssh require password
body: <p>I have successfully installed <code>gitlab</code> on our company's server. And I have tested the ssh way to pull/push the modified files. It works well in my macbook.
  However, My workmates use windows 7 for development.</p>
  
  <p>So when I helped them to config the ssh key for the <code>gitlab</code> according the (gitlab's document)[ <a href="http://doc.gitlab.com/ce/ssh/README.html" rel="nofollow">http://doc.gitlab.com/ce/ssh/README.html</a> ],it doesn't work.</p>
  
  <p>Every time when they push the modified files to the <code>gitlab</code>, it require's them to type password.
  I don't know why is this happening, so please help me out.</p>
