I didn't need the Apple Configurator.  Here's what I did.

First I needed to export my private key with the certificate.  To do that I
used:

      openssl pkcs12 -export -out client.p12 -inkey client.key -in
client.crt -certfile ca.crt

I then installed the CA and the .p12  on the iPhone.  This was then
recoqnised as a valid identity certificate, meaning I could authenticate
with it.
