The master user sets up access rights for DCS administrators on the Extranet. Swisscom draws a functional distinction between a commercial and a technical role. If a user should be able to manage resources for various contracts, then a separate user name is created per contract. When you set up a new user, you can choose between the Customer Admin Commercial (CAC) role and the Customer Admin Technical (CAT) role.
In addition, a “functional” user can be created in the DCS portal for managing cloud ressources via the API. The API user gets direct access to the vCloud Director API by using a user name and password. A secure connection (https) can be used for communication with the API. However, two factor authentication is not supported.
In general, all tasks you can execute in the graphical user interface of the vCloud Director are possible to be executed by an API call as well. Please see the VMware API programming guide for further information.
