similar to: winbind, ntlm_auth and multiple AD domains

Hello I've already tried to post this question some time ago, maybe this time somebody could help me. I try to authenticate users using FreeRadius in few AD forests. The problem is as follows - it is possible to have multiple winbind instances, each binded to a different AD domain and each being interacted by a different instance of ntlm_auth? Or maybe it is possible to bind one winbinnd to

Hello, I'm testing a setup of: 3 DC's all running samba 4.7, freeradius server 3.0.13 using managed switches for 802.1X auth for LAN. All clients are windows 7 or 10 machines, with AD obviously as backend. Windows use for 802.1x settings user and machine "enable single sign-on, authenticate immediately before logon" I issue I face is this: - when user password is expired,

Hey, In samba 4.5.0 update notes it states: /NTLMv1 authentication disabled by default ----------------------------------------- In order to improve security we have changed the default value for the "ntlm auth" option from "yes" to "no". This may have impact on very old clients which doesn't support NTLMv2 yet. The primary user of NTLMv1 is MSCHAPv2 for

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

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

On 29 May 2017 12:32 >When running 'winbindd -SFd5', I see a little more of the problem after I run my two ntlm_auth commands > one after the other. I believe the 'crap' part is an acronym for 'Challenge Response > Authentication Protocol', so why would it be failing? Edit2: wbinfo -a tim.odriscoll%<mypass> works perfectly, with the winbindd debug logs

We have this running but on a DC (Samba 4.10.7). we have this line in /etc/raddb/mods-enabled/mschap. Only this line! DOMAIN is the actual netbio name of the domain. ntlm_auth = "/usr/bin/ntlm_auth --allow-mschapv2 --request-nt-key --username=%{mschap:User-Name:-None} --domain=DOMAIN --challenge=%{mschap:Challenge:-00} --nt-response=%{mschap:NT-Response:-00}" Do you users login in

Guys, Christian, Marco, Thank you very much. Marco, you have the best internal wiki :-) Very very usefull. Whooe.. Most is working atm. And as always the solution was so simpel.. I forgot... To .. Add... ntlm auth = mschapv2-and-ntlmv2-only To the DC's smb.conf. :-/ pretty stupid.. But. So far, it looks good. I've tested now. radtest -t mschap username 'passwd'

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

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,

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 Matthias, > Can you write up some of your findings please? I've not got my setup exactly as I want it yet. Once it's ready and I can document it, I will make it available. I also used the guide from freeradius, as well as many other snippets I found. Now I have to remove them all to see which ones are superfluous..

I've seen that is possible to use switch port blocking with freeradius and cisco switches via 802.1X and EAP protocol. Here is more info: http://wiki.freeradius.org/FreeRADIUS_Active_Directory_Integration_HOWTO What if I don't have switch that supports 802.1X or I want that blocking is done by FreeBSD, not the switch. Because FreeBSD is the firewall or gateway to some networks. Is there

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

We are having the same Samba issue as noted here: http://lists.freeradius.org/pipermail/freeradius-users/2009-November/msg00664.html Has anybody on this list experienced this " \NETLOGON fnum 0xareturned critical error. Error was NT_STATUS_PIPE_DISCONNECTED" error? This wasn't happening until our AD admin upgraded the AD servers to windows server 2008 R2. Also, I see this

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 all, I've configured FreeRADIUS for PEAP and I'm forwarding the NTLM authentication to our Windows Active Directory. I'm using the following script to proxy the MSCHAPv2 NTLM credentials: /usr/bin/ntlm_auth --helper-protocol=ntlm-server-1 >> /tmp/log << @EOF Username: ${1/NTDOMAIN01\\\\} Full-Username: ${1} LANMAN-Challenge: ${2} NT-Response: ${3} . @EOF (This

Hello All, After updating to sernet-samba-4.6.4, ntlm_auth doesn't appear to work for me with challenge and nt-responses. I'm using ntlm_auth in freeradius to authenticate my wifi users against my AD. In sernet-samba-4.2.14 it was working perfectly. My freeradius server is an AD Member, and I've got two other sernet-samba-4.6.4 AD DC's. $ ntlm_auth --request-nt-key
