One of our IPA server is showing these errors in /var/log/messages:

I could paste the the debug logs from sssd but I'm pretty sure that error
in /var/log/messages is the root cause preventing AD ssh login. I did some
research and couldn't find anything revelant.
Any ideas how to fix this ?
It looks like ipaserver.ipa.domain.com
is not a trust
that only trust agents and trust controllers can retrieve trusted domain
object credentials to communicate to AD DCs.
