Description Kurt Seifried 2015-08-14 20:49:00 EDT

Brian Bouterse of Red Hat reports:

Satellite 6 uses a single CA to generate sign all certs; that CA is trusted by 
the Qpid brokers on the server, capsule, dispatch router, httpd, etc. By design,
content hosts only should connect to httpd and the dispatch router. A user with
root access to a content host has access to these certs and could authenticate 
to the server broker or the capsule broker.
