Hi Steve,

If you put
idmap_ldb:use rfc2307 = yes
in your smb.conf then setting the uids gids in AD will guarantee that 
they are the same across your samba4/s3fs servers, because then they 
will get that from AD instead of their private idmap (with a fail-back 
to idmap, if the entry has no uid/gid set).
