[Pki-users] How to install RA on DogTag 10?

I'm running Fedora 21 with Dogtag 10.2.1-3 and trying to get the Registration Authority subsystem to install to enable SCEP ultimately. I installed pki-ra, but when I run "pkispawn -s RA" I get the following: Traceback (most recent call last): File "/usr/sbin/pkispawn", line 579, in <module> main(sys.argv) File "/usr/sbin/pkispawn", line 143, in main parser.init_config() File "/usr/lib/python2.7/site-packages/pki/server/ deployment/pkiparser.py", line 192, in init_config 'pki_instance_name': default_instance_name, UnboundLocalError: local variable 'default_instance_name' referenced before assignment Can anyone point me in the right direction concerning SCEP and DogTag 10? Is there some updated documentation on this somewhere I'm missing? Thanks, Ben
