You link user sign-ins by adding Microsoft Entra ID as an upstream OpenID Connect provider. This keycloak identity brokering microsoft entra id openid connect documentation explains how to pair both systems. Teams often map broad corporate directory groups to admin roles inside their apps. When these roles are too wide, one stolen account can put production data at risk.
How keycloak identity brokering microsoft entra id openid connect documentation works
First, you register a new app inside your Microsoft Entra ID tenant. Microsoft Entra ID gives you a client ID, a client secret, and discovery endpoints. Next, you open your Keycloak realm and add a new OpenID Connect provider. You paste the discovery endpoint URL so Keycloak can read the upstream metadata. Then you add the client ID and client secret from Microsoft Entra ID.
Keycloak creates a redirect URI for this new provider link. You copy that redirect URI back into the Microsoft Entra ID app registration. When a user tries to log in, Keycloak sends them to Microsoft Entra ID. The user signs in there and passes any multi-factor checks on their account. Microsoft Entra ID then sends a signed token back to the Keycloak redirect URI.
Keycloak checks the token signature and reads the user claims inside it. If the user is new, Keycloak creates a local user profile in the realm. You can also set up mappers to read group claims from the token. These mappers attach local realm roles to the user based on their directory groups.
How token mapping handles group claims and role checks
Directory tokens carry claims like user email, group IDs, and job titles. In Microsoft Entra ID, you choose which claims go into the ID token. Teams often send security group IDs so Keycloak knows what the user does. Inside Keycloak, attribute importers and claim mappers read those incoming fields during sign-in.
You can set the sync mode to update roles on every single login. If a user leaves a group in Microsoft Entra ID, Keycloak drops that role. This keeps your local app roles in sync with your main corporate directory. Still, directory groups are often built for broad team structure, not strict database safety.

What native identity setup solves and what it misses
Linking Microsoft Entra ID and Keycloak gives your team one place to log in. When someone leaves the company, you disable their account in Microsoft Entra ID once. That single change blocks their sign-in across every app tied to Keycloak. You also keep multi-factor rules in one central spot for the whole team.
Still, this setup only checks who the person is at the front door. Once a user gets a valid session, the identity system steps out of the way. It cannot see what SQL queries or shell commands an engineer runs next. A developer with a valid role can still run a bad delete query.
Identity tokens also cannot hide sensitive data inside query results during a session. If a table holds emails, phone numbers, card numbers, or national IDs, raw rows return. To control individual commands and rewrite sensitive fields in results, you need runtime controls.
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
Why do roles fail to update when a user logs in again?
Check the sync mode setting on your identity provider mapper inside the realm. If the mode is set to import only, it reads claims on the first login. Switch the mode to force so it updates user roles on every sign-in.
How do I fix a redirect URI mismatch error during login?
Copy the exact callback URL from your Keycloak provider settings page. Paste that full URL into the web redirect settings inside Microsoft Entra ID. Make sure the protocol matches HTTPS and that there are no extra trailing slashes.
Does OpenID Connect brokering filter database queries or mask sensitive data?
No, OpenID Connect only checks user identity and passes claims during the login step. It does not inspect live database queries or Kubernetes commands after sign-in finishes. To rewrite card numbers or emails in query results, you need a runtime tool.
