similar to: NTLM, MSCHAPv2, squid & freeradius...

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've done some further testing, and I have to correct myself. I was (kind of obviously as I think about it) wrong about samba on the freeradius server requiring v. 4.7. What makes all the difference is the method used by mschap. Traditionally in freeradius in mods-available/mschap you'll use something like: ntlm_auth = "/path/to/ntlm_auth --request-nt-key

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 =

Dear All, I'm trying to setup FreeRADIUS to authenticate a machine account to grant access to wifi for domain-connected machines. I think I've got the GPO's set up properly and the CA deployed to the clients, as I'm not getting any errors there. The errors I'm getting are to do with ntlm_auth not authenticating my machine account. Everything looks OK (to me) on the command

Hai, It does not happen often but yes, i also need some help as i cant know everything also and im new with freeradius. Im working on a configuration for samba member + freeradius with ntlm_auth. Why ntlm_auth, because the next one is kerberos and ldap auth to configure.. I want to have some fallback options here and you have to start somewhere. This is running on my new proxy/gateway

> I guess we have to look at the conf files then, first these two: Thank you for the config file snippets. I can confirm mine were almost identical, so I've tweaked them so that they are now exactly the same as yours except for the "--require-membership-of=example\authorization_groupname" line in ntlm_auth. Unfortunately it's still erroring out: (7) mschap: Creating

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, i've configured a new freeradius server for WLAN authentication. My radius server is a domain member on my samba 4.7.12 ADDC. For my mschap configuration i followd this guide: https://wiki.samba.org/index.php/Authenticating_Freeradius_against_Active_Directory. The auth works! I can configure ntlm_auth in two differents way? ntlm_auth = "/path/to/ntlm_auth*--allow-mschapv2*

Hello all, I was not able to find much on this in the archives so I hope someone can help Me with this. Can samba 3.x help the authentication of a Microsoft client authenticating with MSCHAPv2 passwords to my linux box which we use to authenticate a user stored on a Microsoft Active Directory server. The authentication request comes in through RADIUS which I can convert to LDAP,but that

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

Hi, thank you very much for testing everything out. Great work! One question: passchange - which application are working with passchange on radius ? In the moment every user with an expired password is NOT able to use services using radius for authentication (WLAN,VPN). Is there any documentation available ?

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

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,

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
