As I understand from this
it should be possible to setup a trust between FreeIPA and Samba4. My AD
domain is clients.i.rdmedia.com, it's a subdomain of my FreeIPA domain,
i.rdmedia.com. Therefore I added a global forwarder on the Samba AD DC to
one of the FreeIPA replica's and lookup of SRV records in both domains
appears to work.

However when I try to add the trust I get "ipa: ERROR an internal error
has occurred". I ran the trust-add command with full debug logging as
described on https://www.freeipa.org/page/Active_Directory_trust_setup#
Debugging_trust, so I can provide these logs privately upon request.

I suspect some DNS-issue, as right after I try to setup the trust, dynamic
updates stop working on the AD Domain Controller with this error:

tkey query failed: GSSAPI error: Major = Unspecified GSS failure.  Minor
code may provide more information, Minor = Server DNS/fluorine.clients.i.

Many thanks in advance for your assistance.
It would help if you would provide more details on your setup. The above
doesn't give a clue on:
- what are FreeIPA and Samba AD DC versions
- on what OS versions they run, correspondingly
- what DNS zones each of them control
- what commands did you run
