To run a keycloak sync users identity provider flow, link an external directory and map attributes. The system imports user profiles during login or on a scheduled batch job. Platform teams use this setup to manage all employee accounts in one central place. Still, synced group roles often grant broad database and server permissions that stay active forever.
How the keycloak sync users identity provider flow works
Teams link their main directory to Keycloak using standard web protocols like OIDC or SAML. You can also use a user federation link for older directory servers. When a person logs in, the external system sends a signed token with user details. Keycloak reads this token and creates or updates a local user profile.
Attribute mappers control how profile data moves between the two systems. A mapper takes an incoming group name or job title and assigns a local role. You can set the sync mode to import data only once at the first login. You can also set it to overwrite local roles every time the person logs in. For older directory links, background sync jobs pull new accounts and group changes on a timer.
Why attribute mapping requires careful role design
Group mapping makes onboarding fast for growing engineering teams. When a developer joins a team in the main directory, they get their roles right away. When someone leaves the company, disabling their main account blocks new logins across linked apps.
The problem starts when teams map broad directory groups directly to system admin roles. A single group like backend engineering often gets full write permissions on production databases. If a sync mode keeps old roles when directory groups change, users collect extra permissions. Over time, engineers hold standing privileges they only needed for one quick fix months ago.

What identity sync solves and what it leaves open
Syncing user accounts solves the problem of scattered passwords and manual account creation. It gives security teams a single place to check who belongs to which group. It also makes sure that password rules and multi-factor checks happen at the front door.
Still, an identity sync only decides who can log in and which role they hold. It does not check what a user does after the session starts. Once an engineer opens a database shell or server session, the identity tool steps back. It cannot read individual SQL queries or shell commands in flight. It cannot require a peer review before a destructive query runs on a live table. It also cannot rewrite sensitive fields like emails, phone numbers, or card numbers in query results. Relying only on synced roles leaves live data exposed to human error and compromised accounts.
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
What is the difference between user federation and identity brokering?
User federation pulls accounts from directories like LDAP using background tasks and direct queries. Identity brokering redirects users to an external login page using protocols like OIDC or SAML. Brokering updates user data during the login flow instead of running full directory scans.
How do you keep user roles updated when directory groups change?
You must configure the mapper sync mode to update profiles on every login event. If you leave the mode on import only, Keycloak ignores future group changes after first login. Always test role removal to make sure old permissions drop when a user changes teams.
Does disabling a user in the upstream directory kill active database sessions?
No, disabling an upstream account only stops the user from getting new login tokens. Any open database or server sessions stay active until the connection closes or times out. Teams need runtime session controls to cut off active sessions and inspect live commands.
