Have you added the host/krb1.test...@TESTSETUP.COM principal
to the KDC, and created the matching krb5.keytab file on krb1.testsetup.com?

Yes, the host/krb1 pric and krb5.keytab file are present.

Kerberos wants FQDN for host principals. Are they using the FQDN?
The ssh says it could not find the name in the database.
Wireshark or some other network tool can be very helpful too.
It can parse the Kerberos packets for you.

Tail the logs on the kerberos server when you try to log in, and see what ssh
is really asking for. A lot of clients think they know what you really meant
to ask for, and use whatever they get back from reverse DNS as the host name.
If reverse DNS doesn't match what you tried to ssh into, it will fail.
