title: Get Service Principle ID from ARM Template
body: <p>Is it possible to get the <code>ServicePrincipleID</code> via an ARM Template? The examples I am seeing is I need to use some PowerShell to get it then inject it in as a parameter, is this still the case? Ultimately, I am trying to get the <code>ServicePrincipleID</code> of an AD App and then assign it to an instance of KeyVault.</p>
