A nethserver-samba testing package is available. It reverts the effects of the last 2.0.2 release, and restores the default wbclient library from the Samba project.
This means that by default, NTLM auth is still supported, but ACLs can’t be changed from domain workstations /cc @saitobenkei
To enable the support to ACLs from domain workstation (but disable NTLM authentication):
config setprop smb Libwbclient sssd
signal-event nethserver-samba-update
As said, this operation will be soon available from the Server Manager, in Windows file server page.
