Seems like this is to blame: https://fedorahosted.org/freeipa/ticket/4291
The checkin says, "Installation in pure IPv6 environment failed
because pki-tomcat tried to use
IPv4 loopback. Configuring tomcat to use IPv6 loopback instead of IPv4
fixes this issue." However it would seem that in a pure IPv4
environment, this is causing tomcat to fail to load.
