> Currently, once a client is authenticated the generated authentication-token (& cookie)
are valid for a given (service configurable) lifespan.
> Once the authentication-token (& cookie) is issued, the authentication logic will
not be triggered until the authentication-token expires.
> This behavior does not work well with delegation tokens expected behavior where delegation
tokens can be canceled at any time.
> Having ephemeral authentication (which is check on every request) would address this
issue.
