c# – NegotiateStream拒绝非本地管理员的客户端

The server has rejected the client credentials.

除非客户端以具有服务器管理员权限的帐户登录.这是我不想要的.

这是我的客户端代码：

var formatter = new BinaryFormatter();

...

using (var client = new TcpClient(ip,1248))
using (var stream = client.GetStream())
using (var negStream = new NegotiateStream(stream,false))
{
    await negStream.AuthenticateAsClientAsync(CredentialCache.DefaultNetworkCredentials,string.Empty,ProtectionLevel.EncryptAndSign,TokenImpersonationLevel.Identification));
    formatter.Serialize(negStream,"This is a test!");
}

这是我的服务器代码：

var listener = new TcpListener.Create(1248);
listener.Start();

var tcpClient = listener.AcceptTcpClient();
using (var stream = tcpClient.GetStream())
using (var negStream = new NegotiateStream(stream,false))
{
    await negStream.AuthenticateAsServerAsync(CredentialCache.DefaultNetworkCredentials,TokenImpersonationLevel.Identification));
    Console.WriteLine(formatter.Deserialize(negStream));
}

如何配置服务器以接受任何已登录的用户？还有其他需要看的设置吗？是否有另一种方法来验证具有域凭据的流？
