[Samba] Winbind Preauthentication failed

Hi guys!

I started to have the problem above last October, 2th.

I don´t know why and how, because it was saturday. So, my file server
stoped to authenticate against the Samba4 AD.

Today, all shares was stopped and then i restarted my Samba4 AD and the
file server.

All became to work again.

But it im afraid because the problem started by itself.

Thanks!
