OK, if you do 'wbinfo -g', you will get (among others), this:
Enterprise Read-Only Domain Controllers
Group Policy Creator Owners
Read-Only Domain Controllers
Do you really think that your users need to know about all of the above?
As for RFC2307, there is enough in there to get an AD user recognised as
a Unix user, what else do think is required?
Winbind on the Samba4 AD DC works differently, it does show all groups
that have a gidNumber and ignores any that don't.
