[Samba] After the classicupgrade from samba3 to sernet-samba-4.2.1 , users are not able to remote desktop anymore

Fri May 1 07:08:26 MDT 2015

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

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.

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.

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
