Hey, In samba 4.5.0 update notes it states: /NTLMv1 authentication disabled by default ----------------------------------------- In order to improve security we have changed the default value for the "ntlm auth" option from "yes" to "no". This may have impact on very old clients which doesn't support NTLMv2 yet. The primary user of NTLMv1 is MSCHAPv2 for

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

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

Hi, I want to know how to use ntlm_auth with ntlm-server-1 and freeradius, with the users login and password information in ldap. I have read documentation of ntlm_auth (only found the man page), docs and howtos about pptp and squid, i don't found about freeradius, and i'm experimenting with the options of ntlm_auth. I have configured freeradius+ldap+802.1X for a wireless lan, but i

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

Hi, we have updated our samba AD domain from 4.4.x to 4.5.x. The release notes for 4.5.0 included  "NTLMv1 authentication disabled by default". So we had to enable it to get our radius (freeradius) server working (for 802.1x). What would be the best way to change the freeradius configuration in such a way, that we can disable NTLMv1 again. The radius server is used for WLAN

Hello In the organization where I work there are serveral labolatories, each having its own, independent Active Directory Domain (there are no trust relationships between them). We want to build a central 802.1x authentication with users credentials being verified in these AD. To achieve this we configured a central FreeRadius server + winbind and ntlm_auth from Samba suite. It works perfectly

Hello, I am using ntlm_auth called from FreeRADIUS to authenticate users on a network with their Active Directory credentials. The problem I seem to be having is that ntlm_auth is taking longer than it should and I can't seem to get it to go faster reliably. Some background information: Users are connecting to a wireless network using 802.1x. That network sends requests to FreeRADIUS which

I have the following setup in a samba 4.2.1 multi-dc domain DC1 - 10.10.2.50 DC2 - 10.10.2.60 DC3 - 192.168.103.2 I have a site and subnet setup for each DC in Active Directory Sites and Services DC1 server in site DC1 with subnet 10.10.2.50/32 DC2 server in site DC2 with subnet 10.10.2.0/24 DC3 server in site DC3 with subnet 192.168.103.0/24 DC3 has dhcpd setup giving machines on it's

Hi all, I've configured FreeRADIUS for PEAP and I'm forwarding the NTLM authentication to our Windows Active Directory. I'm using the following script to proxy the MSCHAPv2 NTLM credentials: /usr/bin/ntlm_auth --helper-protocol=ntlm-server-1 >> /tmp/log << @EOF Username: ${1/NTDOMAIN01\\\\} Full-Username: ${1} LANMAN-Challenge: ${2} NT-Response: ${3} . @EOF (This

Hello, After update to 4.7.4 on my DC's I see some strange, non-critical (I think) though behaviour. I've noticed that: sometimes running command wbinfo -u doesn't list any of the users, in log i see this: *../source3/rpc_client/cli_pipe.c:568(cli_pipe_validate_current_pdu)* *../source3/rpc_client/cli_pipe.c:568: RPC fault code DCERPC_NCA_S_PROTO_ERROR received from host dc3!*

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 =

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! DOMAIN is the actual netbio name of the domain. ntlm_auth = "/usr/bin/ntlm_auth --allow-mschapv2 --request-nt-key --username=%{mschap:User-Name:-None} --domain=DOMAIN --challenge=%{mschap:Challenge:-00} --nt-response=%{mschap:NT-Response:-00}" Do you users login in

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'

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

I am trying to get FreeRADIUS using Samba's ntlm auth for MSCHAPv2 authentication. I asked this question over on the FreeRADIUS list, and I think the stunned silence means that the folks over there think you guys in the Samba world may be able to help better. I admit it's been a few years since I did any Samba! I have joined my two RADIUS servers (FreeRADIUS 2.0.2, Solaris 10 x86,

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

I can share my notes, we authenticate UniFi clients via Freeradius against Samba AD. We also check group membership which you might or might not need: ## 4 FreeRADIUS ### 4.1 Basics ```bash apt install freeradius freeradius-ldap freeradius-utils # create new DH-params openssl dhparam -out /etc/freeradius/3.0/certs/dh 2048 ``` ### 4.2 Configure Authentication - modify mschap to use winbind,
