title: Cant access property of req.user
body: <p>I'm writing in Node using passport.js to authenticate.</p>
  
  <pre><code>console.log(req.user);
  </code></pre>
  
  <p>returns</p>
  
  <pre><code>{ group: 'CuManager',
    password: 'password',
    username: 'administrator',
    cu_id: 2,
    _id: 569fd3f4328ef124be533caf }
  </code></pre>
  
  <p>but </p>
  
  <pre><code>console.log(req.user.cu_id);
  </code></pre>
  
  <p>returns </p>
  
  <pre><code>undefined
  </code></pre>
  
  <p>I was thinking that cu_id property maybe is not available due to serialization/deserialization, but it's there. I just can't access it.
  How can I do that?
  I need it for</p>
  
  <pre><code>find({cu_id : req.user.cu_id})
  </code></pre>
  
  <p>BTW I can't help thinking passport.js is little overcomplicated (maybe we just don't get along). What else can I use to authenticate users in Node (I use express)?</p>
