This looks like 7.3 update incorrectly added NTP service to IPA server
services (which is displayed as NTP role in `ipa server-show $server`).

A workaround might be to disable the service or remove the service
entry. Disabling is IMHO safer.  IPA CLI tools don't allow
enabling/disabling of services so it must be done by LDAP mod.

It can be done by removing  'enabledService' config value from server's
service entry, e.g.:

dn: cn=NTP,cn=$SERVER_FQDN,cn=masters,cn=ipa,cn=etc,$SUFFIX
changetype: modify
delete: ipaConfigString
ipaConfigString: enabledService
-

Where $SERVER_FQDN is e.g. ipa.example.com and $SUFFIX is e.g.
dc=example,dc=com


Rob, have you originally installed the replica with NTPD and then later
switched manually to chrony?
