I have a regular SSL certificate issued by Network Solutions for a given host, say "host A". Can I create another SSL cert for the wiki host that has the host A cert in its trust path and therefore works for use on the wiki host? Both hosts are in the same domain, for example:
a.host.com <- host A uses purchased SSL cert; CA is Network Solutions
wiki.host.com <- needs its own cert
This question is based on my assumption that since I own a trusted cert from a trusted CA for my domain, then I should be able to use that cert to make others for other hosts on the same domain and those new certs should be trusted since they record the "trust path" up to a trusted CA.
