Why it matters
Provisioning adds, updates and removes users based on an external directory. The difficult part is reconciling identity changes with data ownership and active access, especially when events arrive twice or out of order.
Larger customers expect their directory to determine who belongs in the product. Provisioning turns identity lifecycle events into application membership changes, and failed syncs can leave access behind.
Decisions to make
- Define the stable external identity key and how it maps to local users.
- Decide what deprovisioning does to created resources.
- Separate directory group mapping from your product’s permission model.
- Choose which directory fields can update a local profile or role.
- Define what deprovisioning does to sessions, API keys and owned resources.
Build checklist
- Make create, update and delete operations idempotent.
- Log each provisioning outcome with enough detail to diagnose a mismatch.
- Test reactivation and duplicate events before enabling automatic removal.
- Make incoming provisioning requests idempotent.
- Surface sync errors and last successful reconciliation to administrators.
Common mistakes
- Using email address alone as an immutable user identifier.
- Deleting local product data when a directory user is disabled.
- Assuming a one-time import is equivalent to ongoing provisioning.
