By default, automated desktop pools, manual desktop pools, and farms are created in the root access group, which appears as / or Root(/) in Horizon Administrator. Published desktop pools and application pools inherit their farm's access group. You can create access groups under the root access group to delegate the administration of specific pools or farms to different administrators.

Note: You cannot change the access group of a published desktop pool or an application pool directly. You must change the access group of the farm that the published desktop pool or the application pool belongs to.

A virtual or physical machine inherits the access group from its desktop pool. An attached persistent disk inherits the access group from its machine. You can have a maximum of 100 access groups, including the root access group.

You configure administrator access to the resources in an access group by assigning a role to an administrator on that access group. Administrators can access the resources that reside only in access groups for which they have assigned roles. The role that an administrator has on an access group determines the level of access that the administrator has to the resources in that access group.

Because roles are inherited from the root access group, an administrator that has a role on the root access group has that role on all access groups. Administrators who have the Administrators role on the root access group are super administrators because they have full access to all of the objects in the system.

A role must contain at least one object-specific privilege to apply to an access group. Roles that contain only global privileges cannot be applied to access groups.

You can use Horizon Administrator to create access groups and to move existing desktop pools to access groups. When you create an automated desktop pool, a manual pool, or a farm, you can accept the default root access group or select a different access group.

Note: If you intend to provide access to your desktops and applications through VMware Identity Manager, verify that you create the desktop and application pools as a user who has the Administrators role on the root access group in Horizon Administrator. If you give the user the Administrators role on an access group other than the root access group, VMware Identity Manager will not recognize the SAML authenticator you configure in Horizon 7, and you cannot configure the pool in VMware Identity Manager.
