[Samba] invalid NTLMSSP_MIC / SPNEGO login failed: NT_STATUS_INVALID_PARAMETER

Hello,

since I upgraded my NT4 domain Samba 4.2.11 to 4.2.14 I can no longer 
authenticate
when I access any share.
After that I even upgraded to Samba 4.4.5 but still get the same error:


[2016/10/15 04:42:19.786198,  2] 
../source3/auth/auth.c:305(auth_check_ntlm_password)

   SPNEGO login failed: NT_STATUS_INVALID_PARAMETER


Server: FreeBSD 10.3/64 bit
Clients: Windows 7 64bit

When I downgrade to 4.2.11 everything works again.
An upgrade to DC is currently not an option so I need to stick to NT4 
PDC for a while.

I duplicated the whole server to a VM, so I could test anything and 
wouldn't harm the production server.

Any idea what might the cause?
Do you need more Information?

I have had pretty much the same issue against CentOS 6.x/Samba 3.x DCs
from Samba 4.2.x (CentOS) and 4.4.x (Sernet) File servers.

Please look at BZ#12393 and add your findings:
https://bugzilla.samba.org/show_bug.cgi?id=12303

We upgraded our DCs to 4.4.x and it went away. Are you /really/ still
running actual NT4 DCs? Wow....

Cheers

Alex

[Samba] invalid NTLMSSP_MIC / SPNEGO login failed: NT_STATUS_INVALID_PARAMETER

With the patches for BADLOCK I had to upgrade/patch my domain 
controllers first then upgrade the member servers.

In addition to security fixes, some of the signing defaults changed so I 
think I had to explicitly set

         server signing = No

[Samba] invalid NTLMSSP_MIC / SPNEGO login failed: NT_STATUS_INVALID_PARAMETER

Answering my own question:

I "fixed" it with forcing Windows 7 clients to use LM/NTLM.

using gpedit.msc -> Local Computer Policy - Computer Configuration - 
Windows Settings - Security Settings - Local Policies - Security Options
Changing "LAN Manager authentication level" to "send LM &
NTLM responses"
https://social.technet.microsoft.com/Forums/windows/en-US/aca3e2d0-6d43-431f-bbba-3c01aea6d5a6/changing-authentication-level?forum=w7itpronetworking


So it seems that all current Samba versions doesn't support a classic 
domain (PDC) to use NTLMv2
although it was possible until Samba 4.2.11.
