[ovirt-users] How to create new users other than admin

Hello everyone, I am new to ovirt and would like to apologise if this has been asked before. When I created a cluster of ovirt 4.3, I was presented with the option of creating an admin user. However, we would like to assign different login credentials for our employees with different set of rules. I was able to view the users menu under the Administration > Users. Currently we only have an admin user with internal-authz. When clicking on the add button, I only see "internal-authz" and "*" under namespace. Clicking on Go button simply shows admin user again. I created a new role under the Administration > Configure > Roles, however, there is no option to add new user anywhere. Can you please point me to the right steps for adding new users? Thanks
