If they are a domain admin, they can only administer the domain they are in, correct? i.e.
admin1@mydomain.com could only administer users in mydomain.com
What I'd like is for user
admin1@mydomain.com to be able to administer the domains customerdomain1.com customerdomain2.com, but not mydomain.com or customerdomain3.com.
Is it possible to provision an administrator in this way?
