title: Kerberos Spnego in Spring and Angular frontend + JWT
body: <p>My main goal is to have a Kerberos authentication first and if it fails have an Angular's form page that send a post with username/password to <code>/users/login</code>.</p>
  <p>I have configured pretty much <a href="https://www.baeldung.com/spring-security-kerberos" rel="nofollow noreferrer">as follow</a> in Spring and already made a login/password authentication that sends back a JWT, with guards in the frontend. The frontend is served in the resources folder of Spring.</p>
  <p>Kerberos does not seem to pop up/auto log. Is there something specific to do ?</p>
  <p>Is creating a filter after the Kerberos login the right way to process the authentication in the frontend ?</p>
