Ok, I finally could try it out, and it seems to actually work, but You need samba 4.7 on all machines, not only AD, but also server with freeradius. I didn't get a chance to test it locally, that is samba AD + freeradius on the same server. Setup: 4.7.6 AD server and 4.6.2 samba member + freeradius didn't work (got simple "nt_status_wrong_password") but: 4.7.6 AD and 4.7.1

Hello Andrew, Do you plan to release the patch for "ntlm auth = mschapv2-only" option soon ? We need this on order to use freeradius in a "more safe" scenario than with "ntlm auth = yes" Best Regard, Lulzim KELMENI Direction des Systèmes d'Information Mairie de Saint-Ouen Le 08/06/2017 21:36, Andrew Bartlett via samba a écrit : > On Thu, 2017-06-08 at

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

Hello, I can definately confirm that it's working. My basic setup is: 1) Samba 4.7.6 AD DC (2 of them), compiled from source, on centos 7 2) Freeradius 3.0.13 + samba 4.6.2 as domain member, packages straight from centos repo. // I  tested also on freeradius 3.0.14 and samba 4.7.x smb.conf on the DC is pretty basic, most important is obviously in [globall]:         ntlm auth =

Also I just facepalmed, as I double checked smb.conf right after sending mail, and in samba 4.7 there are new options available for "ntlm auth", as stated in docs: |mschapv2-and-ntlmv2-only| - Only allow NTLMv1 when the client promises that it is providing MSCHAPv2 authentication (such as the |ntlm_auth| tool). So that is is I suppose that special "flag" that is used by

Hello Helper, i found this bug report: https://bugzilla.samba.org/show_bug.cgi?id=12252 At this time i have a samba 4.1.6 Domain Controller and Freeradius-Server. The authentication works pretty well in 4.1.6. Now I built a new Domain Controller from source, version 4.5.0. The configuration like 4.1.6, but now I have an authentication issue. There is no helpfull information in freeradius log

ok, tested it, and it works. so to summarize: on samba ad 4.7.x  in smb.conf "ntlm auth" is set to "mschapv2-and-ntlmv2-only" fr + samba domain member (4.6 and 4.7) in mods-available/mschap you have to add to ntlm_auth --allow-mschapv2 to the whole string OR just use winbind method, which sets correct flag without explicitly adding it. with those settings ntlmv1 is blocked

Hello, i set up a squid proxy that should authenticate users against a samba PDC using winbind. It works fine as long i allow ntlmv1: on the PDC: ntlm auth = yes lanman auth = no client ntlmv2 auth = yes If i restrict the domains authentication method to ntlmv2 - that's what i want - with these settings: ntlm auth = no lanman auth = no client

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 there, I'm trying to get FreeRADIUS to authenticate against my Samba DC. It's Samba 4.7.6-ubuntu running on Ubuntu 18 (kernel version 4.15.0-66-generic). It came nicely packaged with Zentyal, which provides a nice GUI for managing a domain, as well as a CA and lots of cool small features. That same Zentyal also includes support for FreeRADIUS (3.0.16). This is my smb.conf:

I have a server which we use for backing up files. Noticed there was an upgrade available to 18.04.1. Now I cannot connect to from my win7 machine to the Ubuntu share. Any thoughts on what would have changed??? Tom

I set up winbind on one box successfully. Now a friend told me that it might be better to use ActiveDirectoriy (the PDC and all other servers are win2000). What is the difference in both approaches? which is 'better'? I feel that ldap is the more general and cleaner solution. Is that true? My windows-admins will get rid of wins soon. does winbind rely on wins? can libnss-ldap also create
