I've done this, and it is working exactly as designed for me.

You need an entry similar to this:

dn: olcOverlay={5}ppolicy
objectClass: olcOverlayConfig
objectClass: olcPPolicyConfig
olcOverlay: {5}ppolicy
olcPPolicyDefault: cn=Default Password Policy,ou=Policy,dc=example,dc=com
olcPPolicyHashCleartext: TRUE
olcPPolicyUseLockout: TRUE
olcPPolicyForwardUpdates: FALSE
structuralObjectClass: olcPPolicyConfig

This tells LDAP to load the ppolicy overlay.

Here olcDatabase {0} is the config tree read from
${LOCALBASE}/etc/openldap/slapd.d/ with olcDatabase {1} being our LDAP tree.
Then you need to define your password policy at the specified DN within
your main LDAP tree.
