Is it possible to add DNS forward zones to IdM / IPA 2.1.3-9 in RHEL 6.2?

Issue

• We need to add some specific forward zones to the DNS server and would like to know the right way top do this.
• There is no option in the web interface to add a DNS zone with a forwarder that we can see.
  But in the latest version of the upstream IPA command line tool there is an option to add a forwarding zone:

ipa dnszone-add domain.com --forwarder=[ip] --forward-policy=only
