Keycloak Identity and Access Management Documentation
You use the keycloak identity and access management documentation to set up user logins and group roles. You create a realm, add apps as clients, and map roles to tokens. Teams often start by linking their main user store to one shared realm. They give broad roles to whole engineering groups so people can work fast. When roles are too broad, one stolen login gives full reach across many tools. Engineers keep admin rights long after they finish a debug task. How the keycloak identity and access

You use the keycloak identity and access management documentation to set up user logins and group roles. You create a realm, add apps as clients, and map roles to tokens. Teams often start by linking their main user store to one shared realm. They give broad roles to whole engineering groups so people can work fast. When roles are too broad, one stolen login gives full reach across many tools. Engineers keep admin rights long after they finish a debug task.
How the keycloak identity and access management documentation explains realms and roles
Keycloak splits user data and rules into isolated spaces called realms. Each realm holds its own users, groups, apps, and login rules. You register each web app or internal tool as a client in a realm. When a user logs in, Keycloak checks their password and second factor. It then builds a signed token that holds the user profile and role list.
The official guides describe two main types of roles for your teams. Realm roles apply across every app inside that single realm space. Client roles apply only to one specific app or service that you registered. You can also bundle these roles into groups to make management much easier. When a new engineer joins, you put them in the right team group. Their login token then carries all the group claims and role names.
Setting up identity brokering and external user stores
Most teams do not create every user by hand inside Keycloak. Instead, they link an existing directory or an outside identity provider. Keycloak supports standard login flows like OIDC and SAML out of the box. You can map attributes from your main company directory into local token claims. This setup lets users keep one password and one MFA device for work.
During login, Keycloak acts as a central hub for your apps. The app sends the user to the Keycloak login page to verify identity. After the check passes, the user returns to the app with a token. The app reads the token signature to trust who the user is. You can also set token life limits so sessions end on schedule.

Where native identity setups fall short for databases and shells
A native identity setup works well for web apps that read tokens. It verifies who logs in at the start of a browser session. Still, many databases, servers, and CLI tools do not speak OIDC or SAML. Teams often fall back to shared passwords or static keys for those systems. Once a user connects to a database, Keycloak is out of the loop.
Identity tokens decide who gets in the door at login time. They do not inspect what individual queries, commands, or requests do in flight. A user with a valid role can still run a bad drop table statement. They can also pull sensitive emails, phone numbers, or card numbers in bulk. Native login logs show that a user signed in at a certain hour. They do not show the exact SQL statements or shell commands that ran.
Check database and API queries on the wire
Identity tools, roles, and network rules decide who opens a session. Setup alone cannot check what each query does or mask sensitive values in a response once a session starts. When workflows touch Postgres, MySQL, SQL Server, MongoDB, ClickHouse, Kubernetes APIs, SSH, or internal HTTP APIs, hoop.dev runs beside those services as an open-source proxy, a sidecar for your Postgres or API. It inspects requests coming in and results going back on the wire.
Your login details and client tools stay as they are while hoop.dev guardrails refuse bad deletes or drops before they run. On responses, hoop.dev data masking rewrites matched sensitive values in memory. Furthermore, hoop.dev holds SOC 2 Type II, is MIT licensed, and writes every query and decision to an audit trail that generates evidence for HIPAA, GDPR, and PCI DSS. See the source on GitHub.
Frequently asked questions
What is the difference between a realm role and a client role?
A realm role stays global and works across every app in that realm. A client role belongs to one specific app and controls actions inside it.
Can Keycloak control individual SQL queries inside a database session?
No, Keycloak only handles user login and token checks at session start. It does not read or block database queries after the user logs in.
How should teams map company groups to Keycloak permissions?
Sync your main directory groups into Keycloak and attach narrow client roles to them. Avoid giving broad realm admin roles to daily engineering groups.
