I've been spending some time looking for information about this problem and I've found:
- 389DS can connect with other LDAP and rdbms, but RDBMS module is not done.
- Apache DS can connect with RDBMS but I see it's no easy.
- OpenLDAP can connect with RDBMS and only needs configurations.
But, due to I'm not an expert in LDAP, can any tell me how to configure OpenLDAP to work as a proxy for LDAPs and RDBMS (configure the module openldap-server-sql)? I'm not going to save data in OpenLDAP, only use it as a proxy for ldaps, Active Directory LDAP an Oracle RDBMS.
