>                 URL: https://issues.jboss.org/browse/ELY-1547
>             Project: WildFly Elytron
>          Issue Type: Bug
>          Components: Authentication Mechanisms, HTTP
>    Affects Versions: 1.2.4.Final
>            Reporter: Jan Kalina

> When the client sends an initial SPNEGO token with Kerberos as preferred mechanism and includes an invalid kerberos token, then client expects to see the {{WWW-Authenticate}} HTTP header with SPNEGO response {{negTokenResp[ negState = reject ]}}.
> As stated in [SPNEGO specification|https://tools.ietf.org/html/rfc4178#section-4.2.2] negstat is required in first reply:
> {code:borderStyle=dashed}
> negState
> ...
>       This field is REQUIRED in the first reply from the target, and is
>       OPTIONAL thereafter.  When negState is absent, the actual state
>       should be inferred from the state of the negotiated mechanism
>       context.
> {code}
