Can't get FreeRADIUS to work with a Samba DC (MSCHAP)

23 Aug 2019

      Hi all,

I understand my issue is not unique. I have a Samba DC running samba 
4.6.7 on Ubuntu 16.04. I'm now trying to set up FreeRADIUS 3 (3.0.16) 
with SMB 4.7.6 on Ubuntu 18.04 to authenticate against the Samba DC.

Running "radtest aduser password localhost:18120 0 testing123" works.

Running "radtest -t mschap aduser password localhost:18120 0 testing123" 
does not work. I have added this into the smb.conf on both servers:

    ntlm auth = yes

I have been basically following these tutorials:
* https://blog.svedr.in/posts/freeradius-peapv0+mschapv2-howto/

* http://deployingradius.com/documents/configuration/active_directory.html

* 
https://wiki.samba.org/index.php/Authenticating_Freeradius_against_Active_Di...

I would also like to add a comment on the fact that I cannot restart 
smbd on the DC if I put the following line (nothing in the Samba log nor 
syslog):

	ntlm auth = mschapv2-and-ntlmv2-only

I have also tried to set up a Microsoft Radius server (join it to the 
same domain), but got the same results ("wrong password"), so I actually 
suspect there might be something wrong with the Samba DC. Unfortunately, 
I couldn't find so much information on how the DC should be.

Here's my full debug:
