samba - May 2015 - After the classicupgrade from samba3 to sernet-samba-4.2.1 , users are not able to remote desktop anymore

Good Day All

I have a current working configuration of sernet-samba-4.2.1, created by
upgrading from a samba3 PDC using the classic upgrade.

Now, I have added a windows 2008 machine to the domain and I'm using the AD
snap in tools in order to browse the domain.

I can see all the users and groups and they have been imported correctly.
However I am able to remote desktop to the domain machines only with the
user "Administrator at ccdc.lan"; no other user is able to RDP.
Furthermore I am able to add machines to the domain only form the users
Administrator, and not from any other user. I have been using the Group
Policy Manager from the window  administrative tool in order to grant logon
rights to all the users belonging to the Domain User group; furthermore I
have added the users to the group Remote Desktop users, but still I have no
success at all. at the moment the group policies looks like this:

root at ccdc-samba4:/# samba-tool gpo listall
GPO          : {31B2F340-016D-11D2-945F-00C04FB984F9}
display name : Default Domain Policy
path         : \\ccdc.lan\sysvol\ccdc.lan\Policies
\{31B2F340-016D-11D2-945F-00C04FB984F9}
dn           :
CN{31B2F340-016D-11D2-945F-00C04FB984F9},CN=Policies,CN=System,DC=ccdc,DC=lan
version      : 3
flags        : NONE

GPO          : {6AC1786C-016F-11D2-945F-00C04FB984F9}
display name : Default Domain Controllers Policy
path         : \\ccdc.lan\sysvol\ccdc.lan\Policies
\{6AC1786C-016F-11D2-945F-00C04FB984F9}
dn           :
CN{6AC1786C-016F-11D2-945F-00C04FB984F9},CN=Policies,CN=System,DC=ccdc,DC=lan
version      : 7
flags        : NONE


while from the GPM looks like this:

I have also run gpupdate /force from he windows machine and If I do
samba-tool gpo fetch <Domain Policy> I am able to see the changes I have
done from the windows snap in


I am unsure now where the problem lies, are the GPO I have modified being
applied correctly on samba 4 OR is the GPO itself that is not configured
correctly in order to allow RDP (and add machine to domain)? Or any other
issue?

Note that all this was working correctly when I did the same test upgrade
from samba 3 to samba 4.1.6

also I am able to login to every machine in the domain using my domain user
when logging in locally.

Any idea / suggestion?


thanks!

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.

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:

Hello Mario ,

what if you try these : 

dcerpc endpoint servers = epmapper, wkssvc, rpcecho, samr, netlogon, lsarpc,
spoolss, drsuapi, dssetup, unixinfo, browser, eventlog6, backupkey, dnsserver,
remote, winreg, srvsvc
auth methods = sam, winbind, ntdomain, ntdomain:winbind

!! these are only for helping in debugging and should not be used in production.
!! see all the e-mails with subject : Re: [Samba] samba 4.2 RDP problem (solved)
!! and specialy : ma 27-4-2015 8:37 from Andrew Bartlett

so if you want to help debuggen, that would be nice. see bug-id in subject. 
In my case ( debian wheezy, sernet samba 4.2.1, only default GPO ) 
auth methods = sam, winbind is sufficient to login with rdp. 
so if we can find what we need to get GPO workin also, that might help the
developers.

I'll set some GPOs in my test and try again also. 


Greetz, 

Louis
