[Freeipa-users] Can't ssh using GSSAPI delegation from one freeipa client to another consistently

[Ranbir]

Hello,

I have a Fedora 26 desktop joined to a freeipa domain running two ipa
4.5.4-10 servers on CentOS 7.5.1804. I have an odd "problem" I hope
someone here can help me fix.

I can ssh from my desktop to any server in the domain using my password
(i.e. interactive) or GSSAPI. Once on a server, I can ssh to some hosts
in the domain using GSSAPI delegation, but not to others.

When GSSAPI delegation doesn't work, I see this error:

debug1: Unspecified GSS failure.  Minor code may provide more information
Server host/ipa01(a)THEINSIDE.RNR not found in Kerberos database

I think I solved this once before, but it was a very, very long time
ago and I don't have any notes to refer to. 

What am I messing up?
