Use a wildcard domain for your CN Unless each domain had a separate IP You need to specify *.mydaomin.tld as the CN HTH Regards, Serge Fonville Has anyone of you an idea how to get that done, so that the cert can finally be imported/installed on the exchange 2007 server? What I have found so far is that the Exchange server has to get a .cer file. To create a .cer from a certificate, google for openssl pem to cer You would then get http://www.mail-archive.com/openssl-users@openssl.org/msg48437.html and the command would be: openssl x509 -in mykey.pem -inform PEM -out mykey.der -outform DER HTH.
