I think I understand it now ;-)

The debian Samba package used to install winbind as a dependency, it
doesn't now, try running this (as root):

apt-get install winbind libnss-winbind libpam-winbind

The last two packages are the 'glue' between winbind and nsswitch

Ok now I can Look up Domain Users and Groups

root at SRVLNXWINTRA01:/home/data# getent passwd com_spoleto\andrea.rossetti
COM_SPOLETO\andrea.rossetti:*:11212:10513:Andrea
Rossetti:/home/COM_SPOLETO/andrea.rossetti:/bin/false
root at SRVLNXWINTRA01:/home/data# getent group "com_spoleto\\domain
admins"
COM_SPOLETO\domain admins:x:10512:

I can set permission tu shared folder

root at SRVLNXWINTRA01:/home/data# chown root:"com_spoleto\domain
admins" share
root at SRVLNXWINTRA01:/home/data# chmod 2770 share/
root at SRVLNXWINTRA01:/home/data# ls -la
totale 20
drwxrws---  2 root     COM_SPOLETO\domain admins 4096 gen  8 19:39 share

But I have the same problem that I have before when I had sssd instead of
winbind
1. Execute computer management from a Windows domain member client as a domain
admin user (run as com_spoleto\rossetti.admin that is a “domain admins” member
2. Right click on computer management -> connect to another computer ->
srvlnxwintra01 (the Linux server member)
3. I expand “System Tools” -> I expand “Shared Folders” -> click on
“Shares”  right click on “share” -> Click Properties -> click on tab
“Security”. In this tab I have the message “You musr have Read permission to
view the properties of this object” even if I have granted
SeDiskOperatorPrivilege to “com_spoleto\domain admins” Group. But If I execute
“Computer Management” as “com_spoleto\adminserver” user (I explained below the
reason I used this user) I can view/modify the ACLs.
4. Even if I change the permission, using adminserver, adding domainadmins full
control this folder subfolder and files and adding domain users read and execute
this folder subfolder and files, neither a simple user nor a domain admin users
can list the shares in \\servermember
Please help me thanks!
I’ve more and more and more confused. ☹

I tried again, this morning, only point 4 and now I can do things that last
night did not make me do without change any configuration. That night brings
advice? 😊 😊 😊 Seriously… now both the “domain users” and “domain admins” can
list share on \\linuxservermember the “domain admins” full control and the
“domain users” read only.
Do the ACLs configurations take time to be transposed by samba when done from a
vindows client via “computer management” snap-in??
