Installing headpin using katello-conifgure the thumslug oauth provider is not set. I would have expected to see: candlepin.auth.oauth.consumer.thumbslug.secret = SOMEVALUE set
Fixed in Katello master at 01a3a427e036fa8156a9dc867f70f63335f29f60. 0.1.36 or later of katello-configure should have this fix.
