The expected behavior is:

* Every process uses $KRB5_CONFIG, defaulting to /etc/krb5.conf.

* KDC-ish processes (krb5kdc, kadmind, kdb5_util, etc.) also use
$KRB5_KDC_PROFILE, defaulting to something like /var/krb5kdc/kdc.conf.
If both files exist, the contents are merged, with the values from
krb5.conf usually taking precedence (but we're not 100% consistent about
that).

krb5kdc accepts a -r flag telling it what realm(s) to serve, so you may
not need to point it at a config file giving a different default_realm
value.
