You really shouldn't export the sub-CA key.  There are two
alternatives:

1. Use Dogtag to sign the required certificates using the
lightweight sub-CA.  For example:

  pki ca-cert-request-submit --csr-file PATH --issuer-id UUID


2. Generate a keypair and CSR for the Puppet/OpenSSL CA, and create
the certificate in Dogtag using a CA profile.  Dogtag never sees the
sub-CA's private key.

Hope that helps,
