Katello installation with one remote smart proxy

is it possible to install a katello master without proxy and install a remote smart proxy on a different server ?
if the answer is yes, how can i do this ?
Because, in the katello master, if there is no proxy, it is impossible to add a repository. There is this error :
“undefined method `backend_service_type’ for nil:NilClass”
and it is impossible to subscribe the future proxy because there is no file ‘katello-ca-consumer-latest.noarch.rpm’ on the katello master.
Thanks for advance.

While IMHO this should be supported at some point, currently I don’t think it’s supported.
