c# - ews 找不到领域的 KDC

Question

我正在尝试使用 .net 核心获取以下 c# 代码以在 raspberry pi 上运行，该代码在 Windows 上运行良好并且完全按照我的要求执行。但是在 pi 上，它给了我一个涉及 kerberos 的奇怪异常。我过去曾用这个 pi 运行其他 .net 核心程序。

我的代码是:

using System;
using Microsoft.Exchange.WebServices.Data;

namespace Test
{
class Program
{
    static void Main(string[] args)

    {
            // Create the binding to ews
            ExchangeService service = new ExchangeService();
            // Set the credentials for the user
            service.Credentials = new WebCredentials("user@email.com", "password");
            // Set the URL
            service.Url = new Uri("https://email.com/ews/Exchange.asmx");
            // Create a bew email
            EmailMessage email = new EmailMessage(service);
            // Set the recipiant to an email
            email.ToRecipients.Add("user@email.com");
            // Set the subject
            email.Subject = "HelloWorld";
            // Set the body
            email.Body = new MessageBody("This is the first email I've sent by using the EWS Managed API.");
            email.Send();
    }
}
}

但是，当我使用 dotnet core 将其发布到 linux-arm 然后在 pi 上运行它时，出现以下异常

Unhandled Exception: System.ComponentModel.Win32Exception: GSSAPI operation failed with error - An invalid status code was supplied (Cannot find KDC for realm "email.com").

任何帮助都会很棒

如果你需要 GSSApi，你应该安装 gss-ntlmssp，它是 Kerberos 插件的包。如果仍未解决，请查看此 GitHb Issue这似乎是你的。
