Helo friends:
This is my smb.conf file, runing in openSUSE 42.1 system and SAMBA acts 
as a DNS proxy to Bind

# Global parameters
         netbios name = SERVERDOM
         realm = POLRMVAR.MTZ.SLD.CU
         workgroup = POLRMVAR
         dns forwarder =
         server role = active directory domain controller
         server services = s3fs, rpc, nbt, wrepl, ldap, cldap, kdc, 
drepl, winbindd, ntp_signd, kcc
         ldap server require strong auth = no
         idmap_ldb:use rfc2307 = yes

And the client's linux machine (Linux Mint 18.1)configuration I try to join:

            security = ADS
            workgroup = POLRMVAR
            realm = POLRMVAR.MTZ.SLD.CU
            netbios name = el nombre de tu PC en MAYÚSCULA
            add user script = /usr/sbin/adduser --quiet 
--disabled-password --gecos
            log file = /var/log/samba/%m.log
            log level = 1

            # Default idmap config used for BUILTIN and local 
             idmap config *:backend = tdb
             idmap config *:range = 2000-9999

             # Idmap config for domain POLRMVAR
             idmap config POLRMVAR:backend = ad
             idmap config POLRMVAR:schema_mode = rfc2307
             idmap config POLRMVAR:range = 10000-99999

             # Winbind
             winbind separator = +
             winbind enum users = yes
             winbind enum groups = yes
             winbind cache time = 10
             auth methods = winbind
             winbind use default domain = true
             winbind offline logon = false

             # Use template settings for login shell and home directory
             winbind nss info = template
             template shell = /sbin/nologin
             template homedir = /home/usuarios/%U

Kerberos and NTP on the side of client's machine work fine

When I try to join to ADS:

#net ads join -U Administrator
Enter Administrator's password:
ldb: unable to stat module /usr/lib/x86_64-linux-gnu/samba/ldb : No such 
file or directory

[I don't know if is side of server or th linux's client machine and,Why?]

Using short domain name -- POLRMVAR
Joined 'INFORMATICA2' to dns domain 'polrmvar.mtz.sld.cu'

[the machine has already joined to ADS Domaind ?????]

DNS Update for informática2.polrmvar.mtz.sld.cu failed: 

[I was checked the sintaxis in named config file but informatica2 DNS 
update failed: NT_STATUS_UNSUCCESSFUL                                 
               don't have acent]

La caja decía:"Requiere windows 95 o superior"...
Entonces instalé LINUX.
