• If possible, when you construct a request from an existing certificate, you should run the certreq –policy command on a computer that has the input certificate's private key installed. If the private key is unavailable (as is usually the case for cross-certifying non-Microsoft CAs), the PKCS #10 file is NULL-signed and the outer CMS is also NULL-signed. A NULL-signed PKCS#10 is unacceptable to most non-Microsoft CAs.
