Setup Azure App Registration

The recommended way is using a service principle with only the access required for it to document, you can do this by creating an app registration.

1. Begin by creating an App Registration in Azure Entra for the report generator. This ensures that the report generator has precisely the required access, such as organization-wide read permissions or access to a limited set of subscriptions.
2. Assign the API permission https://graph.microsoft.com/Organization.Read.All to the created App Registration.
3. In my tenant, Admin consent is required for this permission.
4. Add a role that allows the App Registration to read an organization. You can do this under Subscription management in Azure and Access Control (IAM). Add Role Assignment, find the App Registration and give it Read access.
5. Assign a secret to the App Registration and make a note of this secret.

With the Azure App Registration now configured, we are ready to proceed.

Configure ARI for Execution

1. Create a dedicated folder for the generated report.
2. Set the environment variable AZURE_TENANT_ID to the tenant ID (found in the App Registration overview for your app).
3. Set the environment variable AZURE_CLIENT_ID to the client ID (found in the App Registration overview for your app).
4. Set the environment variable AZURE_CLIENT_SECRET to the secret noted earlier.
5. Set the environment variable AZURE_AUTHORITY_HOST to https://login.microsoftonline.com/.

Run ARI

Assuming all the environment variables are correctly set, follow these steps:

dotnet tool install --global ARI
ari <AZURE_TENANT_ID> <FOLDER_FOR_REPORT>

By following these steps, you should be able to run ARI successfully for the first time. If you encounter any issues, double-check the Azure App Registration setup and ensure that the environment variables are accurately configured.
