[Samba] One Question .. the question... nobody don´t have answer ..

[Miguel Medalha]

I can see that you are using LDAP.

Do you have the mandatory groups on your LDAP database?

Domain Users
Domain Guests
Domain Admins

Did you set up the appropriate rights with the "net rights grant" command?

Take a look at the smbldap-tools scripts:

Chapter 5 of the "Samba 3 by Example" book can be very useful to you. It 
deals Samba with LDAP configuration.
