Right, thats illegal.

objectclass ( 220.127.116.11.4.1.6921.1.12

SUP ( inetOrgPerson $ officePerson $ evolutionPerson ) STRUCTURAL )
... to your schema and make the object a inetOrgPerson, officePerson,
evolutionPerson, and mHybridPerson. Then it works. You have to seal the
broken objectclass chain.
I assume that this problem is a result of OpenLDAP 2.1.30 being more

Yep. You can't modify the structural objectclass chain of an existing object.

You have to drop and add an object to alter its structural objectclass chain.
This is intended and correct behaviour.
