What is a Subject Alternative Name (SAN) and how do I submit multiple SANs?

 
  1. Subject Alternative Name (SAN): SANs allow you to protect multiple host names with a single SSL certificate.
  2. If your server has more than one alias, we can add a SAN, or multiple SANs, to your certificate to insure that certificate mismatch errors do not happen.
  3. Submitting a CSR with multiple SANs:
    1. When you submit your certificate signing request you will need to select under certificate type InCommon Multi Domain SSL (SHA-2) and add the SANs under the common name.
