See below. Hope I got it right.

I think it happens since something's wrong with the schema of the entry
being modified by heimdal's hdb-ldap. The object class 'krb5KDCEntry'
required for setting the Kerberos attributes with kadmin passwd is missing.

After fixing objectClass of the entry everything work's as expected also
with slapo-unique. But I'd like to see this crash also being fixed.

Ciao, Michael.
