| ===================
| RFC 2830 also specifies a means for additional names to be set in a
| certificate. This is done using the subjectAltName field which is an
| X.509v3 extension of the basic certificate. This field can be used to list
| aliases for a server, shared names in a load-balancing setup, or any other
| desired purpose. A wildcard can also be used, to allow a single
| certificate to match all hostnames within a given domain.
|
| In the openssl.cnf file, the syntax for this extension is
|
| subjectAltName=DNS:alias1.domain1,DNS:host2.domain2,DNS:*.domain3
|
| Any number of names may be specified in the comma-separated list.
| ===================
|
| Maybe can help.

Ok; but, how do I use this information properly. I've already tried
using it but it doesn't seem to work.
Sorry, I'm not an openssl wizard.
I've attached my config file.
Thanks,
James
