The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Azure Managed Identity (MSI) Concepts
**Category**: Azure
**Time Saved**: 1-2 hours debugging identity and RBAC
**Battle-tested**: Yes — multiple Azure deployments
---
## The Problem
You're configuring RBAC for an Azure resource's managed identity. You see `principalId` in one place, `servicePrincipal` in another, and `objectId` elsewhere. Documentation uses these terms interchangeably and you're not sure if they're the same thing.
## Why It's Confusing
A Managed Identity **is** a Service Principal — they're the same object viewed from different angles:
- **Managed Identity**: The Azure resource perspective ("my VM has an identity")
- **Service Principal**: The Entra ID perspective ("there's an app registration")
- **Principal ID / Object ID**: The unique identifier (same value, different names)
## The Rule
**A Managed Identity IS a Service Principal in Entra ID. The `principalId` from the resource matches the Service Principal's Object ID in role assignments.**
## Identity Flow
```

How to install
mdr add fabioc-aloha/alex_skill_mall/azure-identity-msi@git:20260728.80a7ab6mdr add fabioc-aloha/alex_skill_mall/azure-identity-msi@sha256:13a756c5f7392b95Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
