Can you
Reset the SysVol ACLs on every DC.

Also consider upgrading to a recent version of Samba. The early 4.0
releases had some issues about ACLs, etc. I think it was fixed in 4.0.5
already, but I'm not sure any more. And a recent version isn't bad if
you're having problems. Maybe some (other) problems are gone than, too.

Where do the DCs get the UIDs/GIDs from? RFC2307? Then it should be the
same on all DCs, if the way it's configured to retrive the IDs uses the
IDs from the directory. If it's sssd or winbind, configured to create
their own (local) IDs, then it's normal that they differ on each host.

This might be interesting for you:

Can you check
* if the users/groups have a uidNumber/gidNumber attribute?

* if winbind/sssd/nslcd is used to retrieve the accounts on the
DC/Member and post the corresponding config?

If your IDs are not stored in the AD, then they will still be different.

And even if you want to demote the old DCs, you will slip into a further
problem: You have to transfer the FSMO roles first to the new one and
then demote the old. But not everything is transfered and you can't
demote the DC(s) which owned the FSMO roles.
