.net core 通过WCF的SQL Server报表服务器（SSRS）：HTTP请求未经客户端身份验证方案授权'；Ntlm&x27；

我有一个.Net Core 3.1应用程序，它试图通过WCF连接到SQL Server报表服务器，以便按需编程生成报表

但是程序无法针对报表服务器进行身份验证

以下是相关的程序代码：

var binding = new BasicHttpBinding(BasicHttpSecurityMode.TransportCredentialOnly);
binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Ntlm;
binding.MaxReceivedMessageSize = 10485760; //10MB limit

// Create the execution service SOAP Client
var rsExec = new ReportExecutionServiceSoapClient(
    binding,
    new EndpointAddress("http://my-ssrs/ReportServer")
);

// Setup access credentials.
var clientCredentials = new NetworkCredential(
    "MyReportServerUserName",
    "MyReportServerPassword",
    "."
);
if (rsExec.ClientCredentials != null)
{
    rsExec.ClientCredentials.Windows.AllowedImpersonationLevel =
        System.Security.Principal.TokenImpersonationLevel.Impersonation;

    rsExec.ClientCredentials.Windows.ClientCredential = clientCredentials;
}


// ************************************************
// Get following Exception when next line executes.
// ************************************************
await rsExec.LoadReportAsync(null, "/path-to/my-report", null);

当执行最后一行（“rsExec.LoadReportAsync”）时，我得到以下异常：

The HTTP request is unauthorized with client authentication scheme 'Ntlm'. The authentication header received from the server was 'NTLM'.

报表服务器位于同一Windows域上

经过一些研究，我尝试更改ClientCredentialType=HttpClientCredentialType.Windows，但这产生了一个不同的异常，如下所示：

The HTTP request is unauthorized with client authentication scheme 'Negotiate'. The authentication header received from the server was 'NTLM'.

有人对我的尝试有什么建议吗？
