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 =

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

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
