Thanks for the hint. I read that and added "allow nt4 crypto = yes" to
my 4.2.2 PDC. This changed this a little bit but still gives me no 
working 4.2.2 member server. Adding "require strong key = no" and 
"client NTLMv2 auth = no" to the member servers smb.conf but it did
not
change anything.

Here is the log file on the dedicated member server of one client trying 
to connect my member server:

So the problem is appearing here:
[2015/07/06 08:02:47.188335,  0] 
../source3/auth/auth_domain.c:302(domain_client_validate)
   domain_client_validate: unable to validate password for user roland 
in domain MYDOM to Domain controller PDCHOST. Error was 
NT_STATUS_LOCK_NOT_GRANTED.

Why on earth is this happening? When my win7 testmachine is trying
to access the 4.2.2 PDC directly everything is fine and easy. So I 
believe the setup of the PDC is correct.

In the first 2 lines of the log I see the SIDs dumped.
Both for my domain and for my member server.

SID for local machine OSUSE-TEST is: 
S-1-5-21-1853263269-3041869306-167322181
SID for domain MYDOM is: S-1-5-21-290147797-1639656955-1287535205
Join to 'MYDOM' is OK

According to my LDAP the sid for my test member server (OSUSE-TEST) 
should be S-1-5-21-290147797-1639656955-1287535205-61405

Is this maybe a problem? Or is this just the real local sid not the 
domain sid of this machine?

Where shall I look on my 4.2.2 PDC to get more infos on the auth 
problem? The logfiles for the member server are empty on my PDC.

Thanks for all your help! I hope this can be resolved soon!

Just what do you mean by 'According to my LDAP' ?
Have *you* set the SID somewhere?

The local SID is *never* the domain SID, you should use the domain SID.

We have a quite big LDAP and DNS setup. This is one reason why we can't 
switch to samba as AD right now. I made a little php script a decade ago 
which is hooked in as "add machine script" to my PDC. This script 
searches for a free domain sid and creates a machine account in LDAP. 
This works very fine for many years now.

The sid for MYDOM is:
S-1-5-21-290147797-1639656955-1287535205
The sid for my domain member server in this domain is therefore: 
S-1-5-21-290147797-1639656955-1287535205-61405

Here is the ldif for my still not working member server:
# osuse-test$, computers, samba, mydom.com

I have bootstrapped my samba member server before joining the domain with
net setdomainsid S-1-5-21-290147797-1639656955-1287535205
during net rpc join the domainsid ending in -61405 was generated by my 
php script and written to ldap.

On my memberserver I get the following output of these commands:
net getlocalsid 	=> S-1-5-21-1853263269-3041869306-167322181
net getdomainsid 	=> S-1-5-21-290147797-1639656955-1287535205

Is there no way to detect on my PDC what is the problem. Why is my PDC 
Samba rejecting my samba member server...?

Thanks for your help again,

Roland

There doesn't seem to be anything wrong with that ldif.

I take it that you ran 'net getdomainsid' on the PDC and this is the SID
you are using.

Permissions ?? Is the join correct ?

It has been sometime since I did anything major with an LDAP PDC and 
even then I used smbldap tools. It seems strange that 3.6 works but 
4.2.2 doesn't, have you looked into the bug report that was posted in 
this thread ?

 From my understanding, you should be able to use 4.2.x just like 3.6.x, 
but there are slight differences as I pointed out.

What are the problems, reasons etc for not moving to AD, I ask this 
because you seem to be trying to set up a new domain and surely this is 
the very time to upgrade.

Hi Roland,

I had the exact same error, although my setup differed slightly. I tested  
different versions of Samba, and in my case the problem happened only with  
4.2.[0-2]. Samba 4.1.13 does not have the problem, and a build from Git  
master doesn't have it either.

So, you might want to try Samba 4.1.19 or wait for Samba 4.2.3.

Hope this helps,

Roel
