## OpenID Connect

OpenID Connect is another specification, based on **OAuth2**.

It just extends OAuth2 specifying some things that are relatively ambiguous in OAuth2, to try to make it more interoperable.

For example, Google login uses OpenID Connect (which underneath uses OAuth2).

But Facebook login doesn't support OpenID Connect. It has its own flavor of OAuth2.

	conn.Close()
}

func connect(socket string) (*grpc.ClientConn, error) {
	var opts []grpc.DialOption

	opts = append(opts, grpc.WithTransportCredentials(insecure.NewCredentials()), grpc.WithContextDialer(func(ctx context.Context, addr string) (net.Conn, error) {
		var d net.Dialer
		return d.DialContext(ctx, "unix", socket)
	}))

	conn, err := grpc.Dial(socket, opts...)
	if err != nil {
		return nil, err
	}

	mt := monitortest.New(t)
	setupLogging()
	ctx, cancel := context.WithCancel(context.Background())
	defer cancel()

	fixture := connect(ctx)
	ztunClient := fixture.ztunClient
	uid := fixture.uid

	m, fds := readRequest(t, ztunClient)
	// we got am essage from ztun, so it should have observed us being connected
	mt.Assert(ztunnelConnected.Name(), nil, monitortest.Exactly(1))

 2. It attempts to retrieve a connection with that address from the **connection pool**.
 3. If it doesn't find a connection in the pool, it selects a **route** to attempt. This usually means making a DNS request to get the server's IP addresses. It then selects a TLS version and proxy server if necessary.

## OpenID Connect

OpenID Connectは、**OAuth2**をベースにした別の仕様です。

これはOAuth2を拡張したもので、OAuth2ではやや曖昧だった部分を明確にし、より相互運用性を高めようとしたものです。

例として、GoogleのログインはOpenID Connectを使用しています（これはOAuth2がベースになっています）。

しかし、FacebookのログインはOpenID Connectをサポートしていません。OAuth2を独自にアレンジしています。

### OpenID (「OpenID Connect」ではない)

また、「OpenID」という仕様もありました。それは、**OpenID Connect**と同じことを解決しようとしたものですが、OAuth2に基づいているわけではありませんでした。

    val connect = planConnect()

    // Now that we have a set of IP addresses, make another attempt at getting a connection from
    // the pool. We have a better chance of matching thanks to connection coalescing.
    val pooled2 = planReusePooledConnection(connect, connect.routes)
    if (pooled2 != null) return pooled2

    return connect
  }

  /**

        try {
            return connect(loc);
        }
        catch ( UnknownHostException uhe ) {
            throw new SmbException("Failed to connect to server", uhe);
        }
        catch ( SmbException se ) {
            throw se;
        }
        catch ( IOException ioe ) {
            throw new SmbException("Failed to connect to server", ioe);
        }
    }

## استاندارد OpenID Connect

استاندارد OpenID Connect، مشخصه‌ای دیگر است که بر پایه **OAuth2** ساخته شده است.

این مشخصه، به گسترش OAuth2 می‌پردازد و برخی مواردی که در OAuth2 نسبتاً تردید برانگیز هستند را مشخص می‌کند تا سعی شود آن را با سایر سیستم‌ها قابل ارتباط کند.

به عنوان مثال، ورود به سیستم گوگل از OpenID Connect استفاده می‌کند (که در زیر از OAuth2 استفاده می‌کند).
