Unrecognized option "firewall_name" under "hwi_oauth"
<p>After upgrade of my project to symfony 2.8 I get the following error when I push the code to staging server.</p>

<blockquote>
  <p>[Symfony\Component\Config\Definition\Exception\InvalidConfigurationException]
  Unrecognized option "firewall_name" under "hwi_oauth"
  When i remove <code>firewall_name</code> option then I get an error that the option is required.</p>

<p>If someone provide some insight will be much appreciated.</p>
