Hi Rowland Finally, my DC and domain member are in a good state and I was able to authenticate a user using the ntlm_auth program that I ran on the member host. I will describe the solution first because it may be helpful for others. I've also put down couple of things that still perplex me (room for improvement perhaps) I'm running a radius server on a Ubuntu host (named RadSrv) and it

Hi I have a Samba AD-DC (on ubuntu) and I've created a user on it the DC called nileadmin. On the DC, 'pdbedit -w nileadmin' finds the entry and returns nileadmin:4294967295:XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX:6590718693B2E602D30F67B848E08AE9:[U ]:LCT-678A9897: I've joined a member (also a ubuntu host running samba) to the domain. The join is successful. But when I run the

> 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

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]#

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

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 =

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, My goal is to make use of samba 4 and freeradius to authenticate user to use wifi network (WPA2 enterprise). The setup is to setup Samba 4.0.3 in machine A and setup freeradius in machine B.

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

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

Probably is a stupid question, but... I need to implement some 'NTLM auth' (in squid and MSCHAPv2/PEAP on freeradius). It is better to install squid/freeradius in the same host of a DC, or don't bother at all so they can be installed also on a DM? Thanks. -- dott.

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

Hello Andrew, Do you plan to release the patch for "ntlm auth = mschapv2-only" option soon ? We need this on order to use freeradius in a "more safe" scenario than with "ntlm auth = yes" Best Regard, Lulzim KELMENI Direction des Systèmes d'Information Mairie de Saint-Ouen Le 08/06/2017 21:36, Andrew Bartlett via samba a écrit : > On Thu, 2017-06-08 at

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
