Hi all --
RHEL 7.5 as of yesterday and 4.5.4-10.el7_5.3 FreeIPA.
I am randomly seeing: Server not found in Kerberos database
for a host that seems to work just fine and understand that most of
the time you see normal authentications happening for this same host,
so it is not happening all the time. Looking for guidance as to where
to look when one sees this kind of error popping up in the IPA Server
logs.
Can you show exact message from the /var/log/krb5kdc.log on the IPA master?
A most likely reason for this is that you have clients configured with
non-fully qualified domain names and asking for tickets to such servers,
so that you get a request to, say, host/some-hostname@REALM instead of
host/some-hostname.my.domain@REALM.
