C# Dotnet core 2.2/IIS-广告访问问题

我有一个问题，我目前正在工作的应用程序，我希望你们中的一些人能够帮助我

我正在尝试从广告中获取有关登录用户的一些信息（通过windows身份验证）

using (var context = new PrincipalContext(ContextType.Domain))
{
  var user = UserPrincipal.FindByIdentity(context, loginName);
  if (user == null) return new List<string>();
  var groups = user.GetGroups();
  return groups.Select(x => x.SamAccountName).ToList();
}

我使用的是dotnet core 2.2，应用程序托管在IIS 7.5上

请分享错误。您只有

stacktrace行，这些行指示了位置而不是原因。请向域管理员寻求帮助。应用程序池标识通常应设置为域服务帐户，然后它可以与AD对话并查询数据。
