  Thanks Luis

  I've changed the smb.conf as you said, now it looks like this:

  root at ccdc-samba4:~# cat /etc/samba/smb.conf
  # Global parameters
  [global]
          workgroup = CCDC
          realm = CCDC.LAN
          netbios name = CCDC-SAMBA4
          server role = active directory domain controller
          idmap_ldb:use rfc2307 = yes
          dns forwarder = 9.0.138.50
          auth methods = sam, winbind

  [netlogon]
          path = /var/lib/samba/sysvol/ccdc.lan/scripts
          read only = No

  [sysvol]
          path = /var/lib/samba/sysvol
          read only = No
  root at ccdc-samba4:~#

  however from the windows machine when i try to update the group policies,
  I
  am now getting this errors:

  C:\Users\Administrator.CCDC>gpupdate /force
  Updating Policy...

  User policy could not be updated successfully. The following errors were
  encount
  ered:

  The processing of Group Policy failed. Windows attempted to read the file
  \\ccdc
  .lan\sysvol\ccdc.lan\Policies
  \{31B2F340-016D-11D2-945F-00C04FB984F9}\gpt.ini fro
  m a domain controller and was not successful. Group Policy settings may
  not
  be a
  pplied until this event is resolved. This issue may be transient and
  could
  be ca
  used by one or more of the following:
  a) Name Resolution/Network Connectivity to the current domain controller.
  b) File Replication Service Latency (a file created on another domain
  controller
   has not replicated to the current domain controller).
  c) The Distributed File System (DFS) client has been disabled.
  Computer policy could not be updated successfully. The following errors

  To diagnose the failure, review the event log or run GPRESULT /H
  GPReport.html f
  rom the command line to access information about Group Policy results.

  I'm still unable to login with normal users via RDP

  correct.

  bug still exists, just tested also on latest git master.
  see : https://bugzilla.samba.org/show_bug.cgi?id=11061

  temp solution.

  try adding :
  auth methods = sam, winbind
  to smb.conf on the dc and restart the DC.

  Greetz,

  Louis
