I'm 'someone'! ;-)

And, as you know, i've correctly migrated/merged 4 NT domains in an AD
domain some year ago, following also hint from this list. ;-)

As just discussed in this list, while 'classicupgrade' is clearly the
main path for a migration, pose some glitches.
 - there's no 'merge' of multiple domains
 - it is a go/no go tool, there's no way back.

So bulding a new domain is a, surely, longer path, but, at least for
me, smoothest one.

Sure. But ACL are evaluated 'locally' to the server we are connecting,
so we can buld a totally differend domain, with different goups and
ACLs, this is not the point.

The point here is that, as Louis say, something changed in
samba/windows client os and something that worked without trouble with
Win7/samba4.5 two years ago seems does not work now.

I've suggested also to Paolo to:

 + enable on servers/domain members 'winbind use default domain = yes'

 + try to access shares with IP, to (try to) 'disable' kerberos auth

If was Win10, surely also SMB1 have to be enabled, but seems that also
Win7 does not work anymore... so we are asking here...
