RELOPS-1823: import Splunk Logging app and add service principal#291
Merged
Conversation
Microsoft is retiring service-principal-less authentication on March 31, 2026. The third-party multitenant "Splunk Logging" app (31b68eb1-dd36-4317-a95c-9d0e42b18017) acquires ARM tokens in our tenant without a local service principal and will be blocked after that date. Provision an enterprise app in the tenant so the app keeps authenticating after the cutover.
The app flagged by Microsoft is actually Mozilla-owned (created manually 2023-02-01), not third-party. Bring the azuread_application under terraform via import block, preserve existing owners and Microsoft Graph permissions, and add the missing service principal. Refs RELOPS-1823.
