yes, I use the user 'Administrator'. But also I tried with other user I created.

Well, I don't know if this is useful, but only I see is this in the /var/log/syslog file: 
Jan 25 01:15:08 ubuntus samba[27351]: [2017/01/25 01:15:08.780106, 0] ../source4/dsdb/dns/dns_update.c:294(dnsupdate_nameupdate_done) 
Jan 25 01:15:08 ubuntus samba[27351]: ../source4/dsdb/dns/dns_update.c:294: Failed DNS update - NT_STATUS_IO_TIMEOUT 

| * What is your DNS back end?
I am using Bind9_DLZ. 

OTHER problem I'm having is that I can't authenticate proftpd service against my Samba4 AD, however I installed a Windows Server AD and then this works perfectly. So I authenticated Okay against Windows AD. 

In my Samba4.3 AD everythings work fine 'apparently', in fact I joined a Windows client to my domain. 
#samba-tool processes returns this: 
root at ubuntus:~# samba-tool processes 
Service: PID 
dnsupdate 1572 
cldap_server 1565 
rpc_server 1560 
nbt_server 1561 
winbind_server 1570 
kdc_server 1566 
notify-daemon 1609 
ldap_server 1563 
ldap_server 1563 
kccsrv 1571 
samba 0 

Any idea?
