 This example describes how you can use a Service Principal to connect to your directory from within PowerShell. You would use this approach if you wanted to run an unattended script, as from Windows Scheduled tasks.

 ## Give the Service Principal Reader access to the current tenant (Get-AzureADDirectoryRole)
 
 We now have the ability to set the exact access rights this service principal has in your directory. In this example, we'll assign the access rights of the Directory Readers role in Azure AD:
