unfortunately it is broken, nearly every line with a '#' is wrong and
causes libkrb5 to fail parsing the file. I think this is caused by an
issue with authconfig
(https://bugzilla.redhat.com/show_bug.cgi?id=1184639). Please try to
upgrade to authconfig-6.2.8-10.el7 or higher. Nevertheless I think
neither authconfig nor ipa-client-install will be able to fix the broken
file completely and you have to delete the following lines manually.
