Fedora 16 introduced chrony as default client time&date synchronization service: http://fedoraproject.org/wiki/Features/ChronyDefaultNTP Thus, there may be people already using chrony as their time and date synchronization service before installing IPA. However, installing IPA server or client on such machine may lead to unexpected behavior, as the IPA installer would configure ntpd and leave the machine with both ntpd and chronyd enabled. However, since the OS does not allow both chronyd and ntpd to be running concurrently and chronyd has the precedence, ntpd would not be run on that system at all. Make sure, that user is warned when trying to install IPA on such system and is given a possibility to either not to let IPA configure ntpd at all or to let the installer stop and disable chronyd. https://fedorahosted.org/freeipa/ticket/2974
