It should work as long as AD and IPA controlled domains do not overlap. You have to put AD-directly-joined machines to one set of DNS domains and IPA-joined-machines to distinct set of DNS domains.
This is a requirement because you have to have unambiguous DNS domain -> Kerberos REALM mapping. > We have a requirement to keep all servers in our environment using our > primary non-IPA DNS servers for resolution.
