Hi,

you can retrieve the new cert using the GUI. Navigate to Identity tab, 
then Users or Hosts or Services and pick your user, host or service. You 
will find in the "Actions" button a command to "Get Certificate". This 
will open a new window with the content of the cert, that you can 
copy/paste into mycert.pem.

Once you have obtained mycert.pem, you can add it to the NSS database 
that you used previously in order to generate the CSR:
$ certutil -A -d path_to_database -i mycert.pem -t u,u,u -n mycert

Add IPA CA to the nss database:
$ certutil -A -d path_to_database -n "IPA CA" -t CT,, -a < /etc/ipa/ca.crt

Then pk12util and openssl will allow you to extract the key and certs 
through a temp keys.p12 file:
$ pk12util -o keys.p12 -n mycert -d path_to_database
$ openssl pkcs12 -in keys.p12 -out mykey.pem -nodes

The output is mykey.pem which contains the key, the new certificate and 
IPA CA certificate.

HTH,
Flo.
