title: How to: CakePHP logging in without password?
body: <p>I'm trying to find a way to log in user without password.</p>
  
  <p>The reason is that I have phpBB3 forums in my site and the users already log in there. So I'm now building an expansion to the site to have more than just the forum (Using CakePHP). I thought that I could attach automatic account creation to CakePHP when user creates an account to forums (And ofcourse other link for the existing users). So the users would get CakePHP account that has the same username that they have registered in forums. That means that the only way to register to CakePHP part of the site would be to register to the forums first. </p>
  
  <p>Now I'd like to handle the whole logging thing by phpBB3 login so users would still login to forums, and then I'd attach a piece of code that would also login them to CakePHP part of the site with the username they used to login to forums.</p>
  
  <p>This way I could do also put users to their own ACL groups by their status in forums.</p>
  
  <p>Thats what I'm after and I need to know the way to login users this way. <strong>I'm not looking for complete code I'm just looking for an answer that explains how I log in users in CakePHP without them having passwords at all.</strong></p>
  
  <p>I have also looked <a href="http://bakery.cakephp.org/articles/wilsonsheldon/2009/01/13/phpbb3-api-bridge" rel="nofollow">http://bakery.cakephp.org/articles/wilsonsheldon/2009/01/13/phpbb3-api-bridge</a> but it just doesn't quite look what I'm looking for...</p>
