title: omniauth-saml as provider in gitlab
body: <p>I'm trying to get omniauth-saml configured, but I'm not entirely sure what I need to put in app_id and app_secret for this configuration.</p>
  
  <p>I'm using this gem: <a href="https://github.com/PracticallyGreen/omniauth-saml" rel="nofollow">https://github.com/PracticallyGreen/omniauth-saml</a></p>
  
  <p>If I leave those fields blank, of course I get:</p>
  
  <p>Received wrong number of arguments. [nil, nil]</p>
  
  <p>The documentation within the gitlab.yml file links to more documentation about gitlab and omniauth, but that document no longer exists (redirects to old README).</p>
  
  <p>Any assistance would be appreciated, thanks!</p>
