title: How to use servlet container in jenkins
body: <p>I see "servlet container" in jenkins security options. So how can I use this?</p>
  
  <p>In my scenario, I have a team that they have their own username/password, I need ensure they can login using their own account. And we have an account system that manage accounts. So I need to write a java servlet that can connect the account system. </p>
  
  <p>In jenkins, do I need to provide this java servlet? I searched for long time. but I can't find the exact way to use jenkins 'servlet container' security option.</p>
