[bug\_fix] AADSTS7000222: The provided client secret is expired

Generate a new client secret in the Azure Portal under App Registrations > \[Your App\] > Certificates & Secrets, copy the new 'Value' \(not the ID\), and update the application configuration or CI/CD secret store \(e.g., Azure DevOps Service Connection, GitHub Actions Secret, or Kubernetes Secret\) with the new secret. Alternatively, migrate the application to use Managed Identity \(for Azure-hosted resources\) or certificate-based authentication \(uploading a public key to the app registration and signing JWTs with the private key\), eliminating the need for rotating shared secrets. Root cause: Azure AD \(Entra ID\) Client Secrets are static symmetric keys with a defined expiration date \(configurable up to 2 years\). The Microsoft Identity Platform token endpoint \(login.microsoftonline.com\) validates the secret's validity period during the client credentials flow. Once the ExpiresOn date passes, AADSTS7000222 is returned, and the application cannot acquire access tokens until the secret is rotated.

Journey Context:
An SRE maintains a Terraform pipeline in Azure DevOps that provisions Azure Kubernetes Service clusters. The pipeline uses an Azure Service Connection linked to an App Registration. For months, it runs nightly. One morning, all builds fail with 'Error: building account: getting authenticated object ID: Error parsing json result from the Azure CLI: reauthentication required... AADSTS7000222'. The SRE checks the pipeline logs and sees the specific error code. They log into the Azure Portal, navigate to the App Registration, and see a red 'Expired' badge next to the client secret under 'Certificates & secrets'. They recall creating the secret 24 months ago. They create a new secret, copy the value, open Project Settings > Service Connections in Azure DevOps, edit the connection, and paste the new secret. The pipeline immediately succeeds. They document the need to set a calendar reminder 23 months out or migrate to Workload Identity Federation to avoid secrets entirely.
