Redirect admin.domain to Usermin?
When this field is set to Yes (as it is by default), any new virtual
servers will have an admin entry added to their DNS domains, with
the same IP address as the server's website. When http://admin.thedomain.com/ is accessed, the browser will be redirected to Virtualmin on port 10000
of the same domain, to access the administration web interface.
If you want to use a different URL for Virtualmin access (such as one that
you have an SSL certificate for) the redirect URL can be configured in the
following URL for admin redirect field.
