Hello.

A different department purchased an SSL certificate with four domain names (primarydomain.com, www.primarydomain.com, userportal.com and website.com).

Is there any harm in purchasing a wildcard SSL certificate as *.primarydomain.com?  This certificate would be installed on entirely different servers from the certificate installed on the above servers.

I just want to make sure that purchasing a wildcard certificate that would essentially "cover" primarydomain.com and www.primarydomain.com would not cause any issues for say someone browsing to www.primarydomain.com.

I'm 99% sure the answer to this is that there would be no issue at all.  This has to happen in the real world (and test labs) all the time.

Thank you.
