Not quite, if you use '--use-rfc2307' when provisioning a new domain,
two things happen, the ypServ30.ldif is installed into the Samba AD and
'idmap_ldb:use rfc2307 = yes' is added to the new DCs smb.conf, that's
all that happens.
When you join another DC to your new, unless you add it, 'idmap_ldb:use
rfc2307 = yes' isn't added to the DCs smb.conf.
If there isn't 'idmap_ldb:use rfc2307 = yes' in a DCs smb.conf , then
any rfc2307 attributes in AD will be ignored by that DC.

If you use 'idmap_ldb:use rfc2307 = yes' on one DC, you need to use it
on all DCs, remember that you need to sync idmap.ldb between DCs for
sysvol.
