Power Server ID Unified Communications certificates can secure up
to 4 server names that reside on 1 physical server and share the same second
level domain name. When ordering, you have the option to include 3 alternative
server names to be included in the certificate. The certificate issued by
GeoTrust will include these server names along with the server name listed in
the common name of the CSR you submitted, in the Subject Alternative Name
fields.
For example, if you want to secure the following server names:
- www.yourdomain.com
- secure.yourdomain.com
- product.yourdomain.com
- info.yourdomain.com
You must specify the 3 extra names during during the ordering process. You do
not need to add the extra names to your CSR. The number of server names
contained in the Subject Alternative Name (SAN) field is limited to 3.
