eGroupware and Ldap AddressBook

[francesco_r]

I have tried to convert the egroupware addressbook to ldap but without success.
I used these docs to start my work:
http://www.egroupware.org/viewvc/egroupware/branches/1.6/phpgwapi/doc/ldap/README?view=markup
http://anton.frols.com/reviews/egroupware/

Egw needs the rfc2307bis.schema for ldap. Instead ubuntu, like other distribution, use nis.schema as default. Only the latests OpenSuse use the rfc2307bis.schema.
The mayor problem seems to be samba, and in particular the tool smbldap_tools, part of samba package, that support only nis.schema.
Suse/novell, to resolve this issue, developed another app, ldapsmb:
http://en.opensuse.org/Talk:Howto_setup_SUSE_11.1_as_Samba_PDC

I found other useful links of other persons that patched smbldap_tools for the same problem:
http://edin.no-ip.com/content/main-difference-between-nis-schema-and-rfc2307bis-schema
http://edin.no-ip.com/content/smbldap-populate-hack-rfc2307bis-schema-support

But if i understand correctly, ebox write directly in to ldap database so the hack would be in the ebox code base, or i'm wrong?

Can some ebox developer point me in the right direction?

Thank you very much
