title: Sign in user automatically via passport-local
body: <p>I am using <a href="https://github.com/jaredhanson/passport-local" rel="nofollow">passport-local</a> project which is working great. I have however implemented a email verification system now. this works and currently it redirects the user when verified to the sign in page to sign in.</p>
  
  <p>I would however like my system to <em>automatically</em> sign the user in when the user verifies their email.</p>
  
  <p>As it currently stands, a POST must be sent with two fields username and password to the LocalStrategy. I would however like the system to authenticate the user without this.</p>
  
  <p>Anyone know any ideas how this works? Is there a way to manually authenticate a user?</p>
