similar to: ntlm_auth doesn`t work with machine accounts

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'

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 Gaetano, Good plan, I'd be very interested in your work as I am starting to look at symfony here, also! I do have ntlm_auth working perfectly using Samba 4 (and with badlock patches). I use it with freeradius, not squid. An extract from my /etc/raddb/modules/mschap, if it helps: ntlm_auth = "/usr/local/samba/bin/ntlm_auth --request-nt-key

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, 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

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

Hello, I am trying to walk through the following document: http://homepages.lu/charlesschwartz/radius/freeRadius_AD_tutorial.pdf in order to authenticate Cisco router and switch logins against FreeRadius/Active Directory. Using the HowTo, I have successfully joined a FC2 box to our Windows 2003 AD for testing purposes. I have also successfully used the manual ntlm_auth command to authenticate

Hi all, I'm trying to use ntlm_auth as authenticator of the freeradius mschap module. If I use ntlm_auth from command line with username and password, authentication works. If I use the same credentials with mschap on the logs I can see the challenge and nt-response and I can't understand if authentication fails because challenge and response are wrong or because ntlm_auth can't

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 found my problem. From Andrew Bartlett himself "This is not supported against NT4. Only Samba 3.0.21rc1 and AD support this extra flag." To do machine authentication with freeradius, your workstation (supplicant) and samba server must be a member of a 2000/2003 domain. I had the supplicant and samba server still a member of the nt4 domain. Once I changed this, it worked great.

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

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

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 ?

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

I'm trying to move my freeradius server from debian jessie (freeradius 2.2.5+dfsg-0.2+deb8u1 and samba 4.2.14+dfsg-0+deb8u9) in a NT like domain to a new stretch server (freeradius 3.0.12+dfsg-5+deb9u1 and samba 4.8.5+mnu-1~deb9, louis packages). Many things changed. I've followed (also): https://wiki.samba.org/index.php/Authenticating_Freeradius_against_Active_Directory and added in
