title: Does a capistrano deploy.rb file contain server credentials?
body: <p>This is my first time using Capistrano and I am getting server authentication errors right at the start of my deploy:setup stage. I am a PHP user using rvm on a mac.</p>
  
  <p>I noticed my deploy.rb file does not contain the password to my server. It only contains the password to my private git repo. Is there an attribute available for setting the server password so my connection could authenticate?</p>
  
  <p>Do deploy.rb files list server credentials?</p>
