similar to: freeradius + NTLM + samba AD 4.5.x

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

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

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 =

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

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'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

hai,   Please keep it mailing to the list, this way is shows up of others also. A workaround for disabling SMBv1, you can make your server less secure but thats not what i would do. Setting these to enable NTLM v1 again. lanman auth = yes ntlm auth = yes raw NTLMv2 auth = yes I think also this is more a question for the free raduis list, but i would to for a ldap(s) setup. just dont mixup

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

I believe the 'crap' part is an acronym for 'Challenge Response > Authentication Protocol', so why would it be failing?

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

Hi; Samba team say "It is recommended that administrators set these additional options, if compatible with their network environment:" ntlm auth = no I use samba with FreeRadius. I configure "ntlm_ auth = no" but freeradius users not connected to wifi. I use ntlm_auth in FreeRadius side.. best regards

Hi there, I'm trying to get FreeRADIUS to authenticate against my Samba DC. It's Samba 4.7.6-ubuntu running on Ubuntu 18 (kernel version 4.15.0-66-generic). It came nicely packaged with Zentyal, which provides a nice GUI for managing a domain, as well as a CA and lots of cool small features. That same Zentyal also includes support for FreeRADIUS (3.0.16). This is my smb.conf:

Hello Helper, i found this bug report: https://bugzilla.samba.org/show_bug.cgi?id=12252 At this time i have a samba 4.1.6 Domain Controller and Freeradius-Server. The authentication works pretty well in 4.1.6. Now I built a new Domain Controller from source, version 4.5.0. The configuration like 4.1.6, but now I have an authentication issue. There is no helpfull information in freeradius log

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

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
