IdentityServer3 - AccessTokenValidation

Dev build: 

OWIN Middleware to validate access tokens from IdentityServer v3.

You can either validate the tokens locally (JWTs only) or use the IdentityServer's access token validation endpoint (JWTs and reference tokens).

app.UseIdentityServerBearerTokenAuthentication(new IdentityServerBearerTokenAuthenticationOptions
    {
        Authority = "https://identity.identityserver.io"
    });

The middleware can also do the scope validation in one go.

app.UseIdentityServerBearerTokenAuthentication(new IdentityServerBearerTokenAuthenticationOptions
    {
        Authority = "https://identity.identityserver.io",
        RequiredScopes = new[] { "api1", "api2" }
    });
