After looking into setting up ntpd on the IPA servers I decided it
was better just to warn admins. There are just too many valid setups
for time synchronization for us to try to get this right. Additionally,
just installing ntp and accepting the default config will result in
a configuration that is perfectly valid for IPA.
This patch checks if ntpd is running and suggests enabling it if it
is not - for client and server. It also adds some suggested next
steps to the server installation.
The code is still not perfect and rely on a yet unreleased
nss_ldap package that fix dns discovery problems within nss_ldap
itself.
Also the manipulation of krb5.conf need to be improved
