Does upgrading the member servers to Samba 4 mean they can share the uid/gid
mapping the
Samba 4 DCs are currently using?

According to https://wiki.samba.org/index.php/Setup_a_Samba_AD_Member_Server
I would still
need to use:

idmap config DOMAIN : backend = ad

for a member server even under Samba 4. Which would mean I would need to
populate the
uid/gid attributes within AD.
At present, presumably my Samba4 DCs are storing a mapping in the .ldb/.tdb
files in
/usr/local/samba/private (hidden from AD). Is there no way to use the same
mapping on a
member server?
