Reseller option: Force virtual servers to be under domain

Hi,

Today, I've been playing around with the reseller stuff in VirtualMin. When creating/editing a reseller, there is an option to force new virtual servers to be under a specific domain. Let's say foobar.com.

When I log in as that reseller and create a new virtual server, the domain name textfield contains foobar.com as expected. Unfortunatly, if i remove it and use example.org as domain name, it's accepted and a new virtualmin server 'example.org' will be created. I would expect an error or a notify that the 'forced' domain name has been appended to it, so the new domain name is example.org.foobar.com.

Grtz,

Justin
