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 i...

​Hello, I compiled Samba 4.8.2 from the git repository to upgrade my existing samba install, however I'm not sure it has gone correctly and I am having a problem authorizing radius clients that previously succeeded using mschapv2 I set the option in smb.conf ntlm auth = mschapv2-and-ntlmv2-only but running testparm gives me an error set_variable_helper(mschapv2-and-ntlmv2-only): value is not boolean! And also removing the variable and running testparm -v shows the default value of ntlm auth = yes which I'm sure is wron...

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 only works with clear passwords to Active Directory. I still need to compete the MSCHAP challeng...

Is it possible to use NTLMv2 with MSCHAPv2 (using ntlm_auth and winbindd). What do I need to put in the smb.conf to make this work. Thanks a lot for any help. Thanks. Shirish. --------------------------------- Yahoo! Mail Use Photomail to share photos without annoying attachments.

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 : > O...

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.

Currently (samba 4 NT-like domains) i use extensively NTLM auth in freeradius and more mildly in squid, respectively with: Freeradius (mschap module): ntlm_auth = "/usr/bin/ntlm_auth --request-nt-key --domain=SANVITO --username=%{mschap:User-Name:-None} --challenge=%{mschap:Challenge:-00} --nt-response=%{mschap:NT-Response:-00}" squid3: auth_param ntlm program /usr/bin/ntlm_auth

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 Microsoft NPS/AD. I t h i n k I tested it before, but couldn't get it to work and...

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.

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 C...
