You use the azure ad api to check user identities and manage app roles. Teams register an app in their cloud tenant and grant it specific directory permissions. Most engineers start by assigning broad read and write roles to get apps running fast. When those permissions stay too wide, any leaked secret exposes the entire directory to risk.

How the azure ad api handles identity and roles

Microsoft now calls this identity service Microsoft Entra ID, and requests flow through Microsoft Graph. To start, an admin creates an app registration inside the cloud directory tenant. This registration gives the app a unique client ID and a way to prove identity. Admins can upload a certificate or generate a client secret for the app to use. Next, the team picks between two main permission types for the app registration.

Delegated permissions let the app act on behalf of a signed-in human user. App permissions let background services run on their own without a human present. After an admin grants consent, the app requests a token from the identity endpoint. The app then sends this token with each call to read or write directory data.

Scoping directory permissions for engineers and services

Good security starts with keeping app roles and directory scopes as narrow as possible. Many teams grant full directory write scopes during early testing and forget to remove them. A background job that only checks group names needs only a basic read scope. Giving that same job permission to update users or reset passwords creates a major risk.

Admins should also review how teams store and rotate client secrets across their servers. Static secrets sitting in plain text files can leak through code repos or build logs. Using short-lived certificates or managed cloud identities cuts down the risk of stolen keys. Regular audits of granted admin consent help teams spot old apps with excess rights.

Where directory identity checks stop

Setting up the azure ad api solves the problem of proving who a user is. It confirms that an engineer or service belongs to the right group before logging in. It also lets teams shut off a single account when a person leaves the company.

Still, directory tokens only decide who can open the door to a system. Once a user logs into a database or server, the directory steps out of the way. The identity token cannot see which queries run or which tables return sensitive data. A user with valid group membership might still run a bad update on production tables. They might also pull raw emails, phone numbers, card numbers, or national IDs in query results. Directory logs show the initial sign-in event, not the specific commands executed inside the target.

Govern statements and responses across databases and APIs

Good config and scoped roles are needed setup. They do not check single queries in flight or mask sensitive fields in returned rows. Across Postgres, MySQL, SQL Server, MongoDB, ClickHouse, Kubernetes APIs, SSH, and internal HTTP endpoints, hoop.dev runs beside each supported service as an open-source proxy, a sidecar for your database or API.

First, hoop.dev guardrails block banned queries before they run. Then hoop.dev data masking rewrites matched sensitive values in responses in memory. The audit trail records every statement and verdict per resource. Furthermore, hoop.dev holds SOC 2 Type II and is open source on GitHub.

Frequently asked questions

Did Microsoft replace the old Azure AD Graph service?

Yes, Microsoft retired the older Azure AD Graph service in favor of Microsoft Graph. All current apps should send directory requests through the Microsoft Graph endpoint instead.

What is the difference between delegated and app permissions?

Delegated permissions run with the combined rights of the signed-in user and the app. App permissions run as the service itself, often with broad rights across the whole tenant.

Why do directory logs miss database queries and server commands?

The directory only issues the token used to log in at the start of a session. It does not inspect the actual database queries or shell commands sent after login.
