Venafi Trust Protection Platform and up 15.1 and up
With recent changes to Google's Chrome browser, it's necessary for Web Server certificates to have a the DNS SAN filled out all the time. This also conforms to RFC 2818 published in the year 2000 (Click Here for more info). This article displays which CA's automatically include the common name, as a DNS Subject Alternate Name. This means if a user doesn't fill out the SAN field the same as the Common Name, the CA will automatically fill it out for you.
The following CA's have been tested to automatically include the CN as a DNS SAN. Please note that this list is not definite. CA's change; the best thing you can do is test this yourself to confirm your results. Also note, the Microsoft CA requires a checkbox to be set on the CA template in Venafi for this to work.
