similar to: ntlm_auth how to get challenge and nt-response

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*

Dear List, My domain +/- works, so I try to fix rest services based on domain NT/AD.... I use WiFi authorization with PEAP/MSCHAPv2 + freeradius (before migration it works). And after migration autorization does not work. Freeradius server is on samba domain member. So i check domain connectivity: [root at see-you-later samba]# net ads testjoin Join is OK [root at see-you-later samba]#

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 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,

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 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

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

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

> 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

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 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 =

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

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,

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 Tim, Hello samba-people, is there an uptodate guide for authenticating via freeradius somewhere? I have some Ubiquiti APs plus a Cloud Key and I want to authenticate WLAN clients via WPA2-Enterprise instead of a (shared) PSK. It seems like https://wiki.samba.org/index.php/Authenticating_Freeradius_against_Active_Directory is missing some steps (basic setup of freeradius). Can you
