An administrator can take control of a user's vApps, media, and catalogs.
When an administrator retrieves a User element, it contains a link that the administrator can use to take ownership of that user's vApps, media, and catalogs. This action is typically required when a user leaves the organization and an administrator needs to transfer ownership of that user's objects to other users.
This operation requires the rights included in the predefined Organization Administrator role or an equivalent set of rights.
