I wish to have an SSL certificate covering legacy domains (DNS will point all domains to the single web server, our exchange will also handle incoming email from multiple domains). I have found a "multiple wildcard in SAN" SSL provider.
The SSL provider states:
By default, this product will secure 2 wildcard domains (for example: *.yourdomain.com and *.domain.com) and must have a non-wildcard domain (for example: yourdomain.com) listed as the base domain, or Common Name (I will need to "add on another wildcard domain" to the purchase obviously as I need 3x wildcard domains)
As for generating the REQ for the provider (Using IIS 7.5), would I generate a normal SAN request with wildcards in the SAN?
For example, I need to cover *.mydomain1.com *.otherdomain1.org and *.yetanotherdomain.net
so I'm guessing I need a "proper" common name - mydomain1.com then add wildcards as SANs:
My question; is my approach correct?
