Terraform Azure VM 扩展不会将 VM 加入到 Azure 虚拟桌面的 Azure Active Directory

Question

以 https://techcommunity.microsoft.com/t5/azure-virtual-desktop/arm-avd-with-terraform/m-p/2639806 为灵感，我想部署 AVD，但使用 Terraform 将 AAD 加入虚拟机。我根据文章在 Terraform 中定义了一个 VM 和扩展以及 Azure 虚拟桌面部署（主机池、应用程序组、工作区），并且我已经根据将 VM 添加到主机时由 Azure 生成的 ARM 模板调整了扩展池并加入 AAD 'manually'/通过门户。

terraform 已应用且扩展运行成功通过，但 VM 未加入域。

当我查看已部署 VM 上的日志时，主要错误之一是 'DsrCmdAzureHelper::GetTenantId: Unable to get Tenant Id, status code 400'。从 Targeting host name:169.254.169.254, url path: /metadata/identity/info?api-version=2018-02-01 和 'identity not found' 错误如下。

这里有什么问题？以下是扩展的地形，如果需要更多请告诉我。

我在我的环境中测试了它，问题如下：

根据这个 Microsoft Q & A Thread 中的讨论，提到一个键 AADJPrivate 应该出现在路径 HKLM\Software\microsoft\RDInfraAgent 下，如果它不存在，则 VM 将正确添加扩展但无法与 Azure AD 加入域.

因此，作为解决方案，我在代码中更改了一些内容，例如：

The host had custom_rdp_properties as "audiocapturemode:i:1;audiomode:i:0;" instead ,added "audiocapturemode:i:1;audiomode:i:0;targetisaadjoined:i:1;".

Provided auto_upgrade_minor_version = true in the AADLoginForWindows extension.

Added another Custom script extension to add the key AADJPRIVATE for the VM's.

修改后，我尝试了如下内容：

  features {}
