You haven't missed anything. You can't make OpenLDAP, or any other
LDAP server, become a PGP LDAP keyserver. It just doesn't work that
way, as the PGP LDAP keyserver product is actually a LDAP front end to
a PGP backend that does the actual key manipulation work. It may
speak LDAP to the outside world, but it isn't LDAP inside. The way
the schema is written, in fact, it simply cannot be handled with a
regular LDAP server.
There is a *different* schema, available from PGP.com, that allows you
to store keys in a regular old LDAP server. This is not the same
schema as the PGP LDAP keyserver product. GnuPG does not yet support
this new schema.
