All '--use-rfc2307' does, is to make it possible to use rfc2307
attributes, it does not add any rfc2307 attributes.
You need to add these attributes to your users & groups, either by using
the UNIX Attributes tab in ADUC after creating a user, or by creating a
user/group with samba-tool, where you can add the rfc2307 attributes at
the same time.

Then you need to either add uid/gidNumbers and use the winbind 'ad'
backend, or use the winbind 'rid' backend, all the info is on the wiki,
if you are struggling to understand the wiki, just say and we will try
to make it clearer.
