Let Bind track data changes
Integrate new bind-dyndb-ldap features to automatically track DNS data changes: 1) Zone refresh Set --zone-refresh in installation to define number of seconds between bind-dyndb-ldap polls for new DNS zones. User now doesn't have to restart name server when a new zone is added. 2) New zone notifications Use LDAP persistent search mechanism to immediately get notification when any new DNS zone is added. Use --zone-notif install option to enable. This option is mutually exclusive with Zone refresh. To enable this functionality in existing IPA installations, update a list of arguments for bind-dyndb-ldap in /etc/named.conf. An example when zone refresh is disabled and DNS data change notifications (argument psearch of bind-dyndb-ldap) are enabled: dynamic-db "ipa" { ... arg "zone_refresh 0"; arg "psearch yes"; }; This patch requires bind-dyndb-ldap-1.0.0-0.1.b1 or later. https://fedorahosted.org/freeipa/ticket/826
