Please add 'log level = 10' to /usr/share/ipa/smb.conf.empty and re-try
'ipa trust-add', then send me resulting error_log privately.

Samba AD DC versions:
Also CentOS 7, Samba 4.6.2, built from source, configure with one option:
--with-systemd
FreeIPA controls i.rdmedia.com, prod.ams.i.rdmedia.com,
test.ams.i.rdmedia.com and prod.nyc.i.rdmedia.com.
AD controls only clients.i.rdmedia.com and forwards all other DNS queries
to ipa-ams-01.
Samba uses the BIND9_DLZ backend for DNS.
Regarding the commands run: After provisioning the AD domain, I followed
this <https://www.freeipa.org/page/Active_Directory_trust_setup> guide,
except I set up the global forwarder in /etc/named.conf manually.
I got the "ipa: ERROR an internal error has occurred" after running:
ipa trust-add --type=ad clients.i.rdmedia.com --admin Administrator
--password

Hello!
As I understand from this
<https://www.redhat.com/archives/freeipa-users/2016-October/
msg00147.html> thread,
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

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
