@James Chan_110, Thanks for posting in Q&A. For the "Certification authority", we configure the internal fully qualified domain name (FQDN) of your Enterprise CA. In your picture, I think it is "CA.xxx.COM"(to protect your information, I have hide the middle part). For the "Certification authority name", it uses the name of your Enterprise CA. It can be "GOCNCA". For the "Certificate template name", it uses the certificate template name you configured in "Configure certificate templates on the CA" part in the link you provided. You can find the name under the certificate template properties.
Hope the above information can help.
