| It should work without a reboot. I take it you are starting Samba

| 127.0.0.1) ?

Yes, I re-start samba just after provision. 
And yes, I point the nameserver to its real IP address (nameserver 10.53.3.11). 

I've a question about the /etc/hosts file's content: Can I add 
'10.53.3.11 ubuntu.ejemplo.cu ubuntu' 
and keep the entry: '127.0.1.1 ubuntu' ?? 
Should I delete this entry ? 

NOTE: I'm using ubuntu16.04 and installing samba from repo 
root at ubuntu:~# samba -V 
Version 4.3.11-Ubuntu 

Waiting for any idea, Felipe. 
Thanks.

If your Samba machine uses a fixed ip, then it should be in /etc/hosts
As for '127.0.1.1', this usually means you are using Network Manager
and this uses a part of dnsmasq, it is usually recommended to stop
Network Manager doing this (in the conf file) and remove the
'127.0.1.1' line from /etc/hosts
