Domain Mapping and Wildcard SSL Certs on a Multisite


I have installed a Wildcard SSL cert for my Wordpress Multisite- The name of the wildcard domain was *

I have used the domain mapping plugin to change a sub-directory install to, however, the Wildcard SSL doesn't seem to cover this, and I can't purchase an SSL for the domain, as I was told this would not work; it would need to be under a Wildcard cert.

We are attempting to insert the Wordpress site into a custom application on a facebook business page, so the website is available directly from there, and facebook require you to have a SSL cert to insert into a page-

Should this be working? I'm unsure how to do this correctly.
