Bearer token Authorization

Question

I am having a problem with Identity Server 3 and bearer token authentication.

Basically, I can call my Web API methods with an expired access token and the Web API authenticates the user and returns the data.

I have set my client to have an access token lifetime of 360 seconds and this indeed is the case when I check the claim.

How do I go about ensuring my Web API cannot be called with an expired access token. Do I need to set something in my IdentityServerBearerTokenAuthenticationOptions ?

Thanks.

When the request comes in the very first thing we do is check if the identity is authenticated and that the authentication type is "Bearer".

    private static bool RequestIsAuthenticated(HttpActionContext actionContext)
    {
        return (actionContext.RequestContext.Principal.Identity.AuthenticationType == "Bearer" && actionContext.RequestContext.Principal.Identity.IsAuthenticated);
    }

If this returns false we return a HttpStatusCode.Unauthorized.
