After the Liberty server gets the identity of the user, it validates the user in its user registry and performs the authorization checks.

How does SPNEGO work?

The Kerberos service ticket (SPNEGO token) proves the user’s identity and permissions to the service (Liberty server). The client browser then responds to the Liberty server Authenticate: Negotiate challenge with the SPNEGO token that is obtained in the previous step in the request HTTP header.
