SSL: importing a cert and key - howto anywhere?

This is a cryptographically signed message in MIME format.

Hi all,

I have got a basic fedora DS running, and I now need to switch on SSL. I 
have found the SSL docs, which describe in some detail how to create a 
CSR, etc etc.
The missing detail is how to import a certificate and key you already 
have - the admin console seems quite happy to import certs, but it seems 
to be oblivious to the importing of keys.
Anyone know what incantation you have to chant to get DS to import a key 
or a p12 file?
Regards,
Graham
