If the values do not show up, try removing and re-adding the group assignments:
- Open the smallstep provisioning app integration application within OKTA.
- Go to the Assignments tab, select groups, and remove all the groups (remember these group names).
- Wait until the users are removed from the smallstep dashboard (a few seconds).
- Then re-add the groups using the assign button.
- This will trigger a push, and you will see the new uid and gid values in the smallstep dashboard.
