Compatibility between nslcd and samba running as LDAP AD/DC server: services migration

[RhineDevil <tanyadegurechaff [at] waifu.club>]

I tried importing this into samba ad-dc
It failed because it accepts only matching cns, but if I'd do that I don't know 
how to link properly, since there are more than one ports this service may be 
sitting on

As follows:

echo       7/tcp
echo       7/udp
echo       4/ddp

dn: 
CN=echo+ipServiceProtocol=ddp,CN=services,CN=ypServ30,CN=RpcServices,CN=System,DC=mydomain,DC=ldom
cn: echo
objectClass: ipService
objectClass: top
ipServicePort: 4
ipServiceProtocol: ddp

I need advice on the best way to put it understandable by nslcd, given also the 
fact that unlike regular OpenLDAP database, multiple CNs with the same name may 
exist, as long that the internal GUID is different
