Question on how to setup OpenLDAP according to RFC2307

Hi everyone, I am a noobie on LDAP. Here is my problem. I have a tape library that has a web UI that is able to authenticate with and LDAP server. I downloaded and installed OpenLDAP. I have also created some test accounts on the LDAP to make sure it is working properly, and it is. The library documentation says that it is only able to authenticate with LDAP that complys with RFC2307. I read the RFC document and I see that OpenLDAP is already RFC2307 compliant. But I still cannot authenticate the library web UI. So my question is... Is there a structure that the LDAP server should follow in order to comply with RFC2307? For instance, do I need users under certain groups? I used a posixAccount and a posixGroup. Is this correct? Here is my LDIF below. Do I have this setup correct?
