IPA, Active Directory and RHEV

I've been attempting to setup IPA on RHEV for a while now after having trouble with our local Active Directory domain. So what I have done is started work on creating a new domain on this network and configure IPA.

My question is, once you have configured DNS and IPA, what configuration do you need on Active Directory in order for clients using the AD servers as DNS to see the new domain? OR, do I need to simply point clients to this new DNS? 

Once that works, I can add IPA to RHEV...

Thanks!
