[Samba] About recomended configuration

[Rommel Rodriguez Toirac]

 Hello all;
in my network I have a mix of operating systems: Windows XP, Windows 7, Windows 10 and Windows 2008.
 I have instaled a samba4 version 4.9.4 as Active Directory.
 Which is the best configuration to the paramters server min protocol, client min protocol and client max protocol?
 Consider security too.
