[Samba] SMB Conf changes in 4.7

[Arnab Roy]

Hi ,

I have just upgraded samba from 4.5.10 to 4.7.3 and my NTLM auth is
completely broken
on starting winbind its complaining about

Unknown parameter encountered: "winbindd privileged socket directory"
Ignoring unknown parameter "winbindd privileged socket directory"

In our case it needs to be specified on startup via smb.conf and not at
compile time.

This was working fine all this while and there is no mention of these being
deprecated in 4.7.

Can someone comment.

Many Thanks
Arnab
