Sorry, it looks I was wrong...
>From *testInvalidKerberosSpnegoWorkflow* in tests-ldap-kerberos dubugging results GSSContext provides negState response, but we dont use it if connection is already established (=no continuation is needed).
Reopening, working on fix.

> 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.
