No, I would bet that the client is somehow using a different krb5.conf
or is assuming the realm of the server is something other then the
the test realm. i.e. deriving the realm from the DNS domain name.

Try and add to the krb5.conf on the client
[domain_realm]

  host.of.kdc.fqdn = TEST.REALM

Using the FQDN of the test kadmin server, and the name of your test realm.
