title: tramp never stops asking for password
body: <p>I've having serious trouble using tramp on Emacs. I am continuously being asked for my password when I ssh into a server via tramp. This is to the point where it blocks me being able to do anything.</p>
  
  <p>I have looked far and wide on the internet and the most widely used solutions do not seem to work for me.</p>
  
  <ul>
  <li>I have Emacs 24.*</li>
  <li><a href="https://stackoverflow.com/questions/840279/passwords-in-emacs-tramp-mode-editing">I have (setq password-cache-expiry nil)</a></li>
  <li><a href="https://emacs.stackexchange.com/questions/17543/tramp-mode-is-much-slower-than-using-terminal-to-ssh/17579">I have (setq projectile-mode-line " Projectile")</a> </li>
  </ul>
  
  <p>Here is my tramp setup in my .emacs.d for the curious <a href="http://pastebin.com/NJCaa0RH" rel="nofollow noreferrer">http://pastebin.com/NJCaa0RH</a>.</p>
  
  <p>Has anyone else had this problem and can point me in the way of a fix? Or do you see a glaring error in tramp config?</p>
