In Opal, you can use nested groups (also called “group-group propagation”) to add a group to another group and automatically sync memberships between the groups. ## Use cases ### Connect role and resource groups Use nested groups to easily manage access to resources while maintaining existing user group structures. You can: * Define requestable groups containing resources; for example, a group called *Prod Resources*, composed of prod AWS and PagerDuty resources * Define non-requestable groups containing users; for example, a group called *Software Engineers* pulled from an Okta group rule * From the *Prod Resources* detail page under **Group Access**, add the *Software Engineers* group as a nested group, and set an access duration In this example, users in the *Software Engineers* group are then automatically granted access to resources within the *Prod Resources* group, and changes in group membership are automatically pulled from Okta. ### Connect disparate groups You can also use nested groups to connect disparate groups that require access to the same resources, e.g., a Google Group and Okta group, two Okta groups, etc. ## Configuration To set up a nested group: 1. Go to **Inventory** > **Apps** and find the group you’d like to serve as the containing group. The *containing group* contains the *member group* you’ll add. 2. Go to the **Group Access** tab on the containing group. 3. Select **Add Groups** and search for the *member group(s)* to add. 4. Optionally, set the access to be timebound. 5. Select **Add Groups** to save the group. Users in the *member group* are now automatically granted access to any resources or groups in the *containing group.*
