Howdie,
According to /usr/src/UPDATING of a freshly supped 5.3 machine
<snip>
20030505:
Kerberos 5 (Heimdal) is now built by default. Setting
MAKE_KERBEROS5 no longer has any effect. If you do NOT
want the "base" Kerberos 5, you need to set NO_KERBEROS.
</snip>
Will try installing the MIT port from /usr/ports/security/krb5 and setting
KRB5_HOME in /etc/make.conf
