I would also like to add a hint for reviewers how to test:

1) Install refered bind-dyndb-ldap package
2) Configure FreeIPA with DNS using
  2a) ipa-dns-install without any arguments to enable zone refresh
(scenario A)
  2b) ipa-dns-install --zone-notif to enable persistent search (scenario
B)
3) Add new zone using "ipa dnszone-add $ZONE"
4) Use following command to see if the zone is already resolvable:
   $ dig -t soa $ZONE
  4a) scenario A: the new zone does not have to be resolvable
immediately, but in default number of seconds for zone refresh (defaults
to 30)
  4b) scenario B: the new zone should be immediately resolvable
