Setting the policy specifies the host domain names that are imposed on remote access hosts, and users can't change them. Hosts can be shared only using accounts registered on one of the specified domain names. Setting the policy to an empty list or leaving it unset means hosts can be shared using any account. See also RemoteAccessHostClientDomainList. Note: This setting will override RemoteAccessHostDomain, if present. Example value: my-awesome-domain.com my-auxiliary-domain.com
