如果用户有没有管理员权限，我们会得到和你一样的错误.

If user has no admin privileges, we will get the error same as you.

Get-AzureADDomain : Error occurred while executing GetDomains
Code: Authentication_Unauthorized
Message: User was not found
HttpStatusCode: Forbidden

原因是，GetAzureADDomian cmdlet 没有指定租户，因此与用户没有管理员权限的域建立了连接.

为确保连接到预期的 AAD 域，必须在调用 Connect-AzureAD cmdlet 时指定租户 ID.

To ensure connection to expected AAD domian, the tenant ID must specified in call to Connect-AzureAD cmdlet.

PS C:windowssystem32> Connect-AzureAD -TenantId
