similar to: Samba 3 and NTLMv2 support

Hi folks, I have been asked to force NTLMv2 logins to avoid use of LM hashes. To meet the requirement I added some lines to the smb.conf in [Global] (we only have that section anyway - this is purely for domain authentication with an ldap backend): client lanman auth = no client NTLMv2 auth = yes lanman auth = no min protocol = LANMAN2 ntlm auth = no This seemed to work - users

Hi all, In my win2k ADS server(mixed mode), I have set the LAN Manager authentication level to Send NTLMv2 response only\refuse LM & NTLM. In the registry, i also set HKLM\System\CurrentControlSet\Control\Lsa|lmcompatibilitylevel --> level 5 (accepts only NTLMv2). Similarly, i also set HKLM\System\CurrentControlSet\Control\Lsa\MSV1_0\NtlmMinClientSec --> 0x00080000(NTLMv2 Session

Thanks Andrew for the answer. But even if I enable Windows XP to use NTLMv2 (using Regedit on (HKEY_LOCAL_MACHINE/SYSTEM/CURRENTCONTROLSET/CONTROL/LSA LMCOMPATIBILITYLEVEL to 5) and adding "ntlm auth = ntlmv1-permitted" to my smb.conf Still the same error. (No *more connections can* be *made* to this remote computer at this time) in versions higher than 4.10. Any ideas? Best Regards

Hello experts/users, We have a samba server in ubuntu 18.04 LTS with version. apt-cache policy samba samba: Installed: 2:4.7.6+dfsg~ubuntu-0ubuntu2.16 Candidate: 2:4.7.6+dfsg~ubuntu-0ubuntu2.16 All is fine and great. Except one (internet disabled) windows 7 professional PC (sorry we still need to run it for a scientific tool) cannot connect unless I put "ntlm auth = yes" in

I discovered the situation. When attempting to logon from Windows 2008R2 to Samba4 is made we can see in Samba smbd log the following important for understanding the situation lines: [2017/11/20 13:25:52.040094, 2, pid=7100, effective(0, 0), real(0, 0)] ../libcli/auth/ntlm_check.c:430(ntlm_password_check) ntlm_password_check: NTLMv1 passwords NOT PERMITTED for user <username> [2017/11/20

Hi, I'm wondering if samba supports NTLMv2, particullary NTLMv2 session security. But I can't even get NTLM-only to work :(. I'm trying to increase lmcompatibilitylevel, but I can't connect to the samba server anymore when I set it to 2 or higher ("Send NTLM authenication only"). I'm using HEAD CVS of today, and my smb.conf looks like this: [global]

Are there multiple ways that Windows clients encrypt passwords? I'm seeing different behavior between two clients. On one, I can access a Samba share just fine. On the other, using the same username and password to access the same share, I get "incorrect password." Looking for the difference in Samba debug traces, I find it comes down to this: smb_password_ok: Checking SMB

Hi, I'm running Samba 3.5.6 with OpenLDAP 2.4.23 (from Debian Squeeze) as PDC. Everything is working fine (Joining Domains, Log on Users) but I'm not able to Log in as Domain Admin.

Hello all, I guess that everyone knows the message "the trust relation between this workstation and the primary domain failed" when joining Win7 into samba domain. Unfortunately, the same problem appeared few hours/days after the machine was successfully joined in the domain(with reg keys from https://wiki.samba.org/index.php/Windows7) and user able to use it for awhile. Then at

Hi all, I'm running Samba 4.1.6 with Ubuntu 14.04.1 LTS on a Power 8 box.

Hi Rowland, Thank you very much, you were spot on. I had changed the Windows 7 client to LM compatibility level, and now that I reverted it back to 5 (use NTLMv2) it works. It was this registry key that made it start working: [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa] "LmCompatibilityLevel"=dword:00000005 I was ignoring the old LM options and the "NTLMv1" in

Hello. I've just compiled Samba-3.0.0 on Tru-64 5.1b (AKA Digital Unix, AKA OSF) with base security (no shadow passwords) using the native compiler and GNU make.
