> IE checks the server name against each CN's individually.

I found that by experimentation too. I have VBScript sample on how to generate
such a CSR request for IIS using the CryptoAPI.

Furthermore, IE does not care if the CNs have different domains.

e.g.

/CN=www.domain.com/CN=www.domain.net/CN=www.domain.org

-or even-

/CN=www.domain.com/CN=www.cypherpunks.com/CN=www.microsoft.com

You can self-sign such a cert with OpenSSL just fine. Whether you can get a real
CA to sign such a thing is another matter.
