title: Devise - User signed out not in after confirmation
body: <p>I'm following the instructions in this Devise wiki article to customize Devise confirmation in my Rails 3.2.x app.</p>
  
  <p><a href="https://github.com/plataformatec/devise/wiki/How%20To:%20Email-only%20sign-up" rel="nofollow">https://github.com/plataformatec/devise/wiki/How%20To:%20Email-only%20sign-up</a></p>
  
  <p>It's mostly working. After the user signs up, they are signed in as expected. However, when the confirmation link is clicked in the provided email, and the password is entered, the user is redirected to the home page and signed OUT rather than the authentication being persisted.</p>
  
  <p>Any ideas?</p>
  
  <p>Thanks!</p>
