There is this:
Red Hat only supports running Samba as a server with the |winbindd|
service to provide domain users and groups to the local system. Due to
certain limitations, such as missing Windows access control list (ACL)
support and NT LAN Manager (NTLM) fallback, SSSD is not supported.
I do not care if anyone says you can use sssd, the Red-Hat documentation
says otherwise and they should know , they produce sssd.
Do not think that you can use sssd on a Linux client, because as soon as
you add one share, it turns into a server as well, or should we just
tell everyone not to use Samba as a server ??
