similar to: 'winbind use default domain' doesn't appear to work with ntlm_auth

Hi everyone, We just upgraded Samba from 4.4.5 to 4.6.5 and appear to be experiencing a problem with authentication, when the RPC domain is not supplied as part of the username. I have two scenarios where this has cropped up: RADIUS authentication using ntlm_auth Apache HTTP using mod_auth_ntlm_winbind RADIUS authentication: We use the freeRADIUS 'mschap' module to provide

Hello, i set up a squid proxy that should authenticate users against a samba PDC using winbind. It works fine as long i allow ntlmv1: on the PDC: ntlm auth = yes lanman auth = no client ntlmv2 auth = yes If i restrict the domains authentication method to ntlmv2 - that's what i want - with these settings: ntlm auth = no lanman auth = no client

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

Hello, We have samba 3.0.23 installed. We are using free radius to take authentication requests from a nortel vpn server and using ntlm_auth trying to authenticate users against AD. This setup works fine when on the AD side ntlmv1 and ntlmv2 are enabled. (IE. Users can authenticate). However, when only ntlmv2 is enabled users are unable to authenticate. I have searched various places and while

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

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

Hi, I was able to use Unsniff to validate that the incoming 20 byte payloads of audio from the downstream IAX2 trunk was definitely G.729a whilst Asterisk 16.13.0 transcodes to G.711a unnecessarily. Media is confirmed as having been negotiated as g729 on all four streams. Nuance with this call is that it's from a WebRTC client which doesn't transmit any audio, could this be influencing

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

Hi, thank you very much for testing everything out. Great work! One question: passchange - which application are working with passchange on radius ? In the moment every user with an expired password is NOT able to use services using radius for authentication (WLAN,VPN). Is there any documentation available ?
