correctly guest access from local Administrator user...

Domain member:

# Global parameters

	log level = 0
	map to guest = Bad User
	max log size = 5000

 root at vdmsv1:/etc/samba# cat /etc/samba/user.map
 !root = LNFFVG\Administrator LNFFVG\administrator Administrator administrator

domain controller (still samba 4.5):

	netbios name = VDCSV1
	realm = AD.FVG.LNF.IT
	server services = s3fs, rpc, nbt, wrepl, ldap, cldap, kdc, drepl, winbindd, ntp_signd, kcc, dnsupdate
	workgroup = LNFFVG
	log level = 0
	server role = active directory domain controller
	template homedir = /home/%U
	template shell = /bin/bash
	idmap_ldb:use rfc2307 = yes
