rfc2307 being active on the DC is not the same as using the rfc2307
attributes. If all your users have uidNumber attributes and groups have
gidNumber attributes, then you can use the winbind 'ad' backend on Unix
domain members and get the same users and groups as on the DC.
However, if you just have 'idmap_ldb:use rfc2307 = yes' in a DC's
smb.conf and no uidNumber or gidNumber attributes in AD, your users &
groups will be using xidNumber attributes (note, the 'x' in 'xidNumber'
is just that, an 'x', it doesn't replace anything), these numbers are
in the '3000000' range and will never be used anywhere but on a DC.

Yes, how easy it is depends on whether you have uidNumbers/gidNumbers
in AD or not.
