similar to: MSCHAPv2 and NTLMv2

​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

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

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 =

I don't want to use a VPN to solve this one. I am really wondering with (samba 3.x) when the linux box become part of The AD domain does it get a special privileges? > > Hi,i am not sure if i understand yor needs, but maybe this helps > this links guide you to setup a pptp server an client for linux > http://www.poptop.org/ > http://pptpclient.sourceforge.net/ > there

Chaps, I'm trying to get a radius server to authenticate to AD via the samba ntlm_auth program. I've just built samba vsn 3.0.21c with the following config parameters ./configure --with-pam --enable-socket-wrapper --with-ldapsam --with-syslog --with-ldap --with-winbind My smb.conf has global] workgroup = ADIR security = domain password server = 150.237.54.198 realm =

I've setup Samba as an AD-DC on an Ubuntu 22.04. My goal is to use it for testing PEAP MSChapv2 authentication on a Radius server where I want the Radius server to validate the MSChapV2 Challenge-Response sent by the client by talking to the Samba DC ecosystem. I'm using the ntlm_auth program to talk to Samba and it works as expected when I run it on the DC host in a bash shell like so:

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

Ok, I finally could try it out, and it seems to actually work, but You need samba 4.7 on all machines, not only AD, but also server with freeradius. I didn't get a chance to test it locally, that is samba AD + freeradius on the same server. Setup: 4.7.6 AD server and 4.6.2 samba member + freeradius didn't work (got simple "nt_status_wrong_password") but: 4.7.6 AD and 4.7.1

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

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

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]#

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

Would squid and freeradius support LDAP authentication with AD ?   I don't know if you are using NTLM or NTLMv2.

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
