My question is more, why are you defining the SHM key in the DB_CONFIG file
at all, whether through dbconfig statements in slapd.conf, or in the
generated DB_CONFIG file.

There is an shmkey directive you can use in the database section for a given
database, that is what I'd expect you would be using. ;)
