...what im i doing, im following http://deployingradius.com/ Followed these steps, that works out fine. Then we goto : http://deployingradius.com/documents/configuration/active_directory.html for smb.conf i use the config i always us, pretty basic + i added (ass noted on the site) : ntlm auth = mschapv2-and-ntlmv2-only And offcourse i joined this server to the domain. Now im at : Configuring FreeRADIUS to use ntlm_auth for MS-CHAP And i just can not get this to work. What i notice. (0) Found Auth-Type = mschap (0) # Executing group from file /etc/freeradius/3.0/sites-enabled/default (0)...

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!

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' localhost 0 testing radtest -t mschap username at REALM 'passwd' localhost 0 testing These 2 work, thanks for that guys. Now...

...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 /etc/samba/smb.conf ntlm auth = mschapv2-and-ntlmv2-only first note: the server that run freeradius is a domain member, not a DC. 'ntlm auth = mschapv2-and-ntlmv2-only' have to be added to DC(s)? To the server that run freeradius (DC or DM)? It is not clear... Anyway i've tried both with: winbind_username = "%{%{msc...

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]# wbinfo -a test%XXXX plaintext passw...

Most important configuration to make mschapv2 only with ntlmv1 overall disabled (except for mschapv2) is setting in freeradius in /mods-available/mschap: mschap { ..... ntlm_auth...

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* --request-nt-key --username=%{mschap:User-Name} --dom...

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 except for mschapv2, and...

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 --username=%{mschap:User-Name} --domain=DOMAIN--challenge=%{%{mschap:Challenge}:-00} --nt-response=%{%{mschap:NT-Response}:-00}" but starting form...
