| Can you try:

Yes, this command runs perfectly.

| What Windows version is it?
I've tried this with W2K3 and W2k8. 

| What appears in the logs when you try to authenticate using LDAP?
I guess I'm not so good looking into the logs. 
First, do you ask me about the logs in W2k, right? Could you guide me? 
Well, I take a look into Control Panel > Administrative Tools > Events Viewer. but I don't see any error here. 

As I said before, everythings work 'apparently' fine. But, no other services (proftpd, owncloud) can authenticate against my Samba4 AD.
