Think of the subject_rdn as given name for the CA cert and the
subject_base as family name for all subsequent service certs that IPA
automatically generates and signs. While the given names for the
generated service certs may stay hard coded, only the given name for the
CA cert needs to be customizable as requested in the RFE.
Look into the source and you will see that subject_base is used all over
the place and subject_rdn (as replacement for the hard coded
"CN=Certificate Authority") only related to the CA cert. They need to be
kept separate.

CN is mandatory and only emailAddress is a commonly used option for the
"given name" subject_rdn. OU, C and alike belong to the subject_base.
