I think it logs to syslog.
Are you seeing logging configuration that is failing because of the
systemd configuration, or are you saying that if the systemd
configuration is updated *and* a logging stanza is added it would log to
this file?
I would e xpect the kdc to log to /var/log/auth.log out of
Public bug reported:
It'd be nice if `kdc5krb` would log to a file in an intuitive location
like `/var/log/kerberos/kdc.log`. Since the service runs as `root` it's
only necessary to add `/var/log/kerberos` to `ReadWriteDirectories` in
the `systemd` unit.
