      Description

      When Kerberos authentication is set to "Required", Keycloak returns wrong HTTP status during SPNEGO authentication.

      Expected behavior
      As far as I know, a typical steps of SPNEGO authentication is following:
      1. Client web browser does HTTP Get for resource.
      2. Keycloak returns HTTP 401 (Unauthorized) status and the following header: "WWW-Authenticate: Negotiate".
      ...

      Actual behavior
      1. Client web browser does HTTP Get for resource.
      2. Keycloak returns HTTP 400 (Bad request) status and the following header: "WWW-Authenticate: Negotiate".
      3. Browser displays error page saying "Kerberos is not set up. You cannot login."

      Supposed cause
      I suppose, this behavior was introduced in pull request #4687 (see diff).
