Understanding Okta Provisioning and Group Push Race Conditions
Last Updated:
Overview
Adding a user to an App Assignment group and a Group Push group simultaneously causes a race condition. Okta processes these actions asynchronously, often causing the Group Push to fail if the downstream application lacks the provisioned user. Administrators must control the execution order via Okta Workflows or manual retries to ensure successful provisioning and updates to group membership.

Solution
Why does a race condition occur between provisioning and Group Push?
Okta does not have an internal mechanism that pauses Group Push to wait for user provisioning (App Assignment) to complete. When an administrator adds a user to both groups simultaneously, Okta initiates two independent, asynchronous background tasks:
- Task A (App Assignment): Initiates a System for Cross-domain Identity Management (SCIM) call to create and link the user profile in the downstream application.
- Task B (Group Push): Initiates a SCIM call to update the group membership in the downstream application.
Because these tasks run asynchronously, Task B often executes before Task A finishes. When the Group Push process attempts to add the user to the downstream group, Okta looks for the user in the target application. If the provisioning process remains incomplete, the push fails, and Okta generates a Group Push error in the Admin Console.
Why does Okta require separate groups for App Assignment and Group Push?
Okta explicitly mandates that these groups be separated in the official documentation. Using a single group for both functions causes the Okta database to struggle when reconciling the local Okta group membership with the downstream application group membership during a single synchronization event. This conflict results in overlapping API loops and phantom push errors. Separating the groups eliminates the database conflict and allows administrators to explicitly control the execution order.
What methods control the execution order?
Because Group Rules fire simultaneously, they do not serve as the optimal tool for assigning a user to both groups for automated provisioning. Enforce the correct order of operations using one of the following methods.
Implement Okta Workflows to automate the process and prevent the race condition by following these steps.
- Assign the user to the App Assignment group.
- Use a Wait/Pause card, or actively poll the user application status until Okta reports the user as successfully provisioned.
- Assign the user to the Group Push group.
Alternatively, manage the race condition using manual retries or staggered rules by reviewing these options.
- Manual Retry: Allow the simultaneous Group Rules to execute and the race condition to occur. Okta provisions the user successfully, but the Group Push generates an error. Navigate to the Push Groups tab of the application and select Retry All Groups to resolve the backlog after provisioning completes.
- Staggered Group Rules: Base the Group Push rule on an attribute that populates only after a successful downstream writeback. This method depends entirely on the specific SCIM capabilities of the application and requires precise timing.
