KSP(密钥存储提供程序）未通过凭据提供程序在登录时加载

我正在创建一个 Windows 凭据提供程序，以使用本文中所述的证书登录到 Windows 域。这意味着创建一个自定义 KSP，LsaLogonUser 将在创建身份验证包时调用该 KSP。

我设法创建自定义 KSP 并在直接调用 LsaLogonUser 的独立应用程序中成功测试了它。基本上创建身份验证包并将其传递给LsaLogonUser，加载KSP，调用一堆函数并对用户进行身份验证，在状态代码和加载的用户配置文件上返回成功结果。

但是，当我在凭据上的 GetSerialization 期间使用相同的身份验证包时，KSP 甚至不会加载，并且我在 ntsStatus 上收到 ReportResult（NTSTATUS ntsStatus， NTSTATUS ntsSubstatus， ....） 报告的0xc000000d（参数不正确）。

这是我在测试中使用的 GetSerialization 代码：

    HRESULT AOCredential::GetSerialization(
    CREDENTIAL_PROVIDER_GET_SERIALIZATION_RESPONSE *pcpgsr,
    CREDENTIAL_PROVIDER_CREDENTIAL_SERIALIZATION *pcpcs,
    PWSTR *ppwszOptionalStatusText,
    CREDENTIAL_PROVIDER_STATUS_ICON *pcpsiOptionalStatusIcon
)
{
    UNREFERENCED_PARAMETER(ppwszOptionalStatusText);
    UNREFERENCED_PARAMETER(pcpsiOptionalStatusIcon);
    HRESULT hr;
    ULONG ulAuthPackage;
    hr = RetrieveKerberosAuthPackage(&ulAuthPackage);
    if (SUCCEEDED(hr))
    {
        InitialiseKerbCertificateLogon(&pcpcs->rgbSerialization, &pcpcs->cbSerialization); // this package actually worked when calling LsaLogonUser function directly (the KSP gets loaded and the authentication succeeds)
        pcpcs->ulAuthenticationPackage = ulAuthPackage;
        pcpcs->clsidCredentialProvider = CLSID_CallsignProvider;
        *pcpgsr = CPGSR_RETURN_CREDENTIAL_FINISHED;
    }
    return hr;
}

我的问题是，为什么在Windows登录期间直接从LsaLogonUser调用身份验证包而不是从凭据提供程序调用时加载KSP。
