Bug 1095025

Description of problem:
Attempting to install IPA on a IPv6 only system causes error where CA does not start up.

Version-Release number of selected component (if applicable):
freeipa-server-3.3.5-1.fc20.x86_64
Also seems to apply to the RHEL versions of IPA

How reproducible:
always

Steps to Reproduce:
1. Set up system with only a IPv6 address, no IPv4 addresses
2. Ensure a valid DNS server is in /etc/resolv.conf
3. Ensure that a valid /etc/hosts entry exists.
4. /usr/sbin/ipa-server-install --hostname=<systems valid hostname> -r EXAMPLE.COM -n example.com -p <pw> -P <pw> -a <pw> --ip-address=<IPv6 global address>
