In Constellix you have the ability to add sub-users and configure their control permissions.
Click on Management
Navigate to Users, under your Manage option
Click on ‘Add User’
Edit your user’s information and proceed to save your changes
Finally, you can set permissions for each user within your Constellix account. You can see that User1 only has access to the Billing Information for this account, whereas user3 has access to Constellix DNS, Sonar and RTA.
