title: Laravel 4: Auth credentials with two optional value to user type
body: <p>I have 3 types of users:</p>
  
  <ol>
  <li>Client</li>
  <li>Admin</li>
  <li>Super Admin</li>
  </ol>
  
  <p>Now, I need to allow both <code>admin</code> and <code>super admin</code> to login in my admin portal how ever to implement the authentication we are going to put in array form our credentials like:</p>
  
  <pre><code>$creds = array('username'=&gt;Input::get('uname'),'password'=&gt;Input::get('pwd'),'usertype'=&gt;$utype);
  </code></pre>
  
  <p>How can I allow both <code>admin</code> and <code>super admin</code> in <code>Auth</code> if I am only allowed to declare <code>usertype</code> once in my <code>$creds</code> array?</p>
