Add/modify/remove permissions for users and groups on vCenter Server inventory objects
As described previously, a permission is a match between an object in the vCenter object hierarchy, a user (or a group), and a role.
With vSphere Web Client, you can manage vCenter permissions for users or groups by selecting one object from one of the vCenter inventories and then clicking on the Permissions tab:

With the selected toolbar, you can add, edit, or remove selected permissions.
For Global Permissions, the toolbar remains the same, but you must select the Global Permissions menu that is located at Home | Administration | Access Control:
Remember that global permissions can span more vCenter servers in the same SSO domain.
When you add or modify a permission, you need to select one or more users (or groups), a specific role, and whether the permission will be propagated in the objects hierarchy (refer to the next section for more information):
