IPA implements read/write permissions for DNS record or zones. Provided set of permissions and privileges can, however, only grant access to the whole DNS tree, which may not be appropriate. Administrators may miss more fine-grained permissions allowing them to delegate access per-zone. Create a new IPA auxiliary objectclass ipaDNSZone allowing a managedBy attribute for a DNS zone. This attribute will hold a group DN (in this case a permission) which allows its members to read or write in a zone. Member permissions in given zone will only have 2 limitations: 1) Members cannot delete the zone 2) Members cannot edit managedBy attribute Current DNS deny ACI used to enforce read access is removed so that DNS privileges are based on allow ACIs only, which is much more flexible approach as deny ACIs have always precedence and limit other extensions. Per-zone access is allowed in 3 generic ACIs placed in cn=dns,$SUFFIX so that no special ACIs has to be added to DNS zones itselves. 2 new commands have been added which allows an administrator to create the system permission allowing the per-zone access and fill a zone's managedBy attribute: * dnszone-add-permission: Add per-zone permission * dnszone-remove-permission: Remove per-zone permission https://fedorahosted.org/freeipa/ticket/2511
