title: Capistrano SSH::AuthenticationFailed, not prompting for password
body: <p>I've been using capistrano successfully for a while now and all of a sudden in every project I've lost the ability to deploy.</p>
  
  <p>Environment:</p>
  
  <ul>
  <li>os X (Mavericks)</li>
  <li>ruby 1.9.3p194</li>
  <li>rvm (locally, not on server)</li>
  <li>rails 3.2 and up</li>
  <li>RubyGems 1.8.25</li>
  </ul>
  
  <p>I'm not using rsa_keys or anything I want capistrano to prompt for user and password. Suddenly it has decided not to ask for a password, but does ask for user. Then it rolls back and gives me the following error.</p>
  
  <pre><code>[deploy:update_code] exception while rolling back: Capistrano::ConnectionError, connection failed for: sub.example.com (Net::SSH::AuthenticationFailed: Authentication failed for user user@sub.example.com)
  connection failed for: sub.example.com (Net::SSH::AuthenticationFailed: Authentication failed for user user@sub.example.com)
  </code></pre>
  
  <p>This has occurred on my personal laptop and my iMac at work. It occurs when deploying to two different servers (both linux)</p>
  
  <p>I'm completely at a loss here. Any ideas?</p>
