I have done similar with back-sql

database        sql
suffix          "dc=example,dc=com"
rootdn          "cn=Manager,dc=example,dc=com"

database        relay
suffix          "ou=sql-user,o=avci,c=de"
relay           dc=example,dc=com
overlay         rwm
rwm-rewriteEngine       on
rwm-rewriteMap <rules>

database        hdb
suffix          "o=avci,c=de"
rootdn          "cn=admin,o=avci,c=de"
