      • An SSL certificate issued for www.coolexample.com is not valid for secure.coolexample.com. If you want your SSL to cover secure.coolexample.com, make sure the common name submitted in the CSR is secure.coolexample.com.
      • If you are requesting a wildcard certificate, add an asterisk (*) on the left side of the Common Name (e.g., *.coolexample.com or *.secure.coolexample.com).
    • Organization — The name in which your business is legally registered. The organization must be the legal registrant of the domain name in the certificate request.

      Note: If you are enrolling as an individual, enter the certificate requester's name in the Organization field, and the Doing Business As (DBA) name in the Organizational Unit field.

    • Organizational Unit — Use this field to differentiate between divisions within an organization (such as "Engineering" or "Human Resources").
