Hello Alexander, thanks Alexander for these configuration snippets. Which version of Samba are you using? Is this on debian bullseye? Is the FreeRADIUS server installed on a DC or on a Domain Member? (I just tested the latter). is "ntlm auth = yes" OK for the DCs and the domain member or does it have to be "mschapv2-and-ntlmv2-only" for all servers (DCs + Member)? It

Hi Matthias, we?re using Debian Bullseye with the backports repo. So version is a mixture of - Samba version 4.17.3-Debian - Samba version 4.17.7-Debian We?ve installed it directly on the DC?s as well. In my opinion using "ntlm auth = yes? should be fine. Did you try using a simple RADIUS secret? In my experience long secrets or ones containing special characters don?t work very well. I

Hi Alexander, I'm terribly sorry. We didnt have the "ntlm auth" parameter configured on the DCs at all. I added it and it just works. Thanks for your help. Now I just need to figure out how I can make WLAN-specific LDAP-Group authentication. e. g. production WLAN needs LDAP group "wlan_production" and management WLAN needs the "wlan_management" group. I

Hi, I want to know how to use ntlm_auth with ntlm-server-1 and freeradius, with the users login and password information in ldap. I have read documentation of ntlm_auth (only found the man page), docs and howtos about pptp and squid, i don't found about freeradius, and i'm experimenting with the options of ntlm_auth. I have configured freeradius+ldap+802.1X for a wireless lan, but i

I can share my notes, we authenticate UniFi clients via Freeradius against Samba AD. We also check group membership which you might or might not need: ## 4 FreeRADIUS ### 4.1 Basics ```bash apt install freeradius freeradius-ldap freeradius-utils # create new DH-params openssl dhparam -out /etc/freeradius/3.0/certs/dh 2048 ``` ### 4.2 Configure Authentication - modify mschap to use winbind,

Chaps, I'm trying to get a radius server to authenticate to AD via the samba ntlm_auth program. I've just built samba vsn 3.0.21c with the following config parameters ./configure --with-pam --enable-socket-wrapper --with-ldapsam --with-syslog --with-ldap --with-winbind My smb.conf has global] workgroup = ADIR security = domain password server = 150.237.54.198 realm =

Hello, We have samba 3.0.23 installed. We are using free radius to take authentication requests from a nortel vpn server and using ntlm_auth trying to authenticate users against AD. This setup works fine when on the AD side ntlmv1 and ntlmv2 are enabled. (IE. Users can authenticate). However, when only ntlmv2 is enabled users are unable to authenticate. I have searched various places and while

It is an issue that I myself would also like to solve. I found multiple threads in samba and freeradius mailing lists. It seems that every couple of months there is question like this either here on FR mailing list and all point down to the same issue, that is: freeradius uses ntlm_auth (even when using winbind with newer freeradius versions, it also in the end uses ntlm_auth). And since

Hi, I am using samba 3.2.2 with freeradius . I have joined the domain & able to authenticate users with ntlm_auth. If in ADS-2003 I configure the Remote Access Permission for the user ( User-properties->Dial-in ) as Deny then if I use the "ntlm_auth --username=user --password=password" I get NT_STATUS_OK. What could be the reason for this behavior , or is there any patch

Hello, I am using ntlm_auth called from FreeRADIUS to authenticate users on a network with their Active Directory credentials. The problem I seem to be having is that ntlm_auth is taking longer than it should and I can't seem to get it to go faster reliably. Some background information: Users are connecting to a wireless network using 802.1x. That network sends requests to FreeRADIUS which

I am trying to get FreeRADIUS using Samba's ntlm auth for MSCHAPv2 authentication. I asked this question over on the FreeRADIUS list, and I think the stunned silence means that the folks over there think you guys in the Samba world may be able to help better. I admit it's been a few years since I did any Samba! I have joined my two RADIUS servers (FreeRADIUS 2.0.2, Solaris 10 x86,

Hi everyone, We just upgraded Samba from 4.4.5 to 4.6.5 and appear to be experiencing a problem with authentication, when the RPC domain is not supplied as part of the username. I have two scenarios where this has cropped up: RADIUS authentication using ntlm_auth Apache HTTP using mod_auth_ntlm_winbind RADIUS authentication: We use the freeRADIUS 'mschap' module to provide

Hihi So I have a really strange problem. I am running Centos 7 with Samba purely for ntlm_auth against winbind services (squid/radius auth etc). Its been working fine till we found a strange bug with the ntlm_auth executable. If the username has a "w" at the end it throws out a syntax error see below test: # ./ntlm_auth --username=lblaauw username must be specified! Usage:

Hi guys/gals. I'm brand new to this list, been working with Linux for several years, and have occasionally set up samba file servers before in a "hi-i'm-wide-open-so-anyone-can-read/write-to-my-shares" mode for temporary storage in data recovery scenarios. At the moment, I'm working on a project that involves FreeRADIUS authenticating against a Win2k/2k3 AD server using the
