RE: MS-CHAP2-Response is incorrect

3 Sep 2021

      Thats exacly why you have to use : 

ntlm_auth = "/path/to/ntlm_auth --allow-mschapv2 --request-nt-key  ... 
( added : --allow-mschapv2 ) 

And set in smb.conf global secion on all samba servers using freeradus 
and any 4.2+ samba Ad-DC. 

ntlm auth = mschapv2-and-ntlmv2-only

Dont forget, if you use it, in freeradius.. passchange section. 

mods-available/mschap:
passchange {
ntlm_auth = "/path/to/ntlm_auth 
--helper-protocol=ntlm-change-password-1 --allow-mschapv2

Hi Daniel
Have you seen this: 
https://support.microsoft.com/en-us/topic/ntlm-authentication-
fails-with-0xc0000022-error-for-windows-server-2012-windows-8-
1-and-windows-server-2012-r2-after-update-is-applied-a4b23900-

Could it be relevant to your problem?

Subject: MS-CHAP2-Response is incorrect
Hello,
Our FreeRadius to Active Directory authentication is no 
longer working. It was working up until about a month ago, we 
upgraded the domain controller from 2008r2 to 2012r2. After 
that we started having issues when people connecting to the 
VPN would get “Access denied – wrong user name or password”. 
Even though the server never appeared to lose domain 
connection, adding the FreeRadius server back to the domain 
with “net join” would band aid it for a week and then the 
same error message would come up. However that band aid 
hasstopped working.
The only thing that’s changed is the domain controller so I’m 
not sure if it needs to be tweaked, but I wanted to ask in 
here if anyone’s had the same issue dealing with Windows 
server 2012R2/FreeRadius AD authentication and had to tweak 
anything on FreeRadius and/or the Windows server?
I have researched the issue and have not found any 
information at this point that has resolved the issue.
This is the error message in the /var/log/freeradius/radius.log file:
ERROR: (0) mschap: ERROR: Program returned code (1) and 
output 'Access denied (0xc0000022)'
Auth: (0) Login incorrect (mschap: Program returned code (1) 
and output 'Access denied (0xc0000022)'): [penny001] (from 
client checkpoint port 0)
Setup:
Windows 2012R2 domain controller
Ubuntu 16.04.6 LTS (We plan to migrate to 20.04 later this 
year once our on-season dies down and get this current one 
back working) Freeradius 3.0.15 Samba 4.3.11+dfsg-0ubuntu0.16.04.34
I setup AD authentication with FreeRadius a few years ago, so 
I do not remember all the sources I used except this one
