Let me clear up this confusion:
The important thing is to have Kerberos REALM = uppercase version of DNS
domain containing all the SRV records (let's call this DNS domain "primary"
DNS domain).

If this condition is fulfilled, AD trusts and other auto-detection procedures
will work. You can add arbitrary number of FreeIPA clients to "secondary" DNS
domains as long as they do not overlap with AD-managed domains and it will
just work.

Does it clear the confusion?
