NW65sp4a, EDir

I'm looking at buying a wildcard certificate and have a question about using
it with Edirectory and non-Edirectory systems. Some of the systems I will be
using it on are NetWare, Netmail, Apache on NetWare, Apache on non-NetWare
(MAC, Linux, Unix)

Is this possible?
Do I need to create the CSR with openssl or IManager?
If I use openssl, how do I import the private key / public key in to
If I use IManager, how do I export the private key.

I did a export using Imanager and got the PKF file and converted it into a
PEM, but the private key shows to beRSA encrypted.
