Only if you have Admin access, you will be able to see this feature.
You can restrict which Department(s) should have the ability to create users.
On this window, we selected which Access Group(s) within Driver Department can add users.
Then, log out from your session and log back in - this time using a Driver Department user and password - and try to create a new user by clicking Add User.
You can see only the Access Groups and Departments previously selected on Restrict.
To create a user you just need to fill up the form and click Save.
Now, the user has been created.
