Azure ARM Template: “ObjectID” with Azure Key vault policy assignment

Hi all,

When you author ARM Templates, and you are deploying a Key Vault and setting the Access Policies via the template, be careful about the content of the objectID.

  "accessPolicies" : [                    {                        "tenantId": "xxxxx-30d9-xxxxx-8015-ddddddd",                        "objectId": "rrrrr-tttt-rrrr-rrrr-tttttt",                        "permissions": {
               "keys": ["all"],
               "secrets": ["all"] 
                }
                    },

If you are assigning the policy to a user account, use the objectId value found on Azure AD:

If you are assigning the policy to a Service Principal, use the ObjectID of the Application that you can get from the Enterprise Application blade, and not the App Registration blade.
