We've got a question on the certificate and the SAN part. Can i put as common name my domain name (eg: example.tld) and use the SAN part to protect my subdomaine (eg: www.example.tld) ?
Actually because the common name used is www.example.tld instead of example.tld we are not protected on example.tld (which is not acceptable).
We could redirect everybody from example.tld to the subdomaine www.example.tld, but we would like to be protected on both domain name.
Is this a common configuration ? Do our certificates company should accepts our requests ?
