Can't get FreeRADIUS to work with a Samba DC (MSCHAP)
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: main { security { user = "freerad" group = "freerad" allow_core_dumps = no } name = "freeradius" prefix = "/usr" localstatedir = "/var" logdir = "/var/log/freeradius" run_dir = "/var/run/freeradius" } main { name = "freeradius" prefix = "/usr" localstatedir = "/var" sbindir = "/usr/sbin" logdir = "/var/log/freeradius" run_dir = "/var/run/freeradius" libdir = "/usr/lib/freeradius" radacctdir = "/var/log/freeradius/radacct" hostname_lookups = no max_request_time = 30 cleanup_delay = 5 max_requests = 16384 pidfile = "/var/run/freeradius/freeradius.pid" checkrad = "/usr/sbin/checkrad" debug_level = 0 proxy_requests = yes log { stripped_names = no auth = no auth_badpass = no auth_goodpass = no colourise = yes msg_denied = "You are already logged in - access denied" } resources { } security { max_attributes = 200 reject_delay = 1.000000 status_server = yes } } radiusd: #### Loading Realms and Home Servers #### proxy server { retry_delay = 5 retry_count = 3 default_fallback = no dead_time = 120 wake_all_if_all_dead = no } home_server localhost { ipaddr = 127.0.0.1 port = 1812 type = "auth" secret = <<< secret >>> response_window = 20.000000 response_timeouts = 1 max_outstanding = 65536 zombie_period = 40 status_check = "status-server" ping_interval = 30 check_interval = 30 check_timeout = 4 num_answers_to_alive = 3 revive_interval = 120 limit { max_connections = 16 max_requests = 0 lifetime = 0 idle_timeout = 0 } coa { irt = 2 mrt = 16 mrc = 5 mrd = 30 } } home_server_pool my_auth_failover { type = fail-over home_server = localhost } realm example.com { auth_pool = my_auth_failover } realm LOCAL { } radiusd: #### Loading Clients #### client localhost { ipaddr = 127.0.0.1 require_message_authenticator = no secret = <<< secret >>> nas_type = "other" proto = "*" limit { max_connections = 16 lifetime = 0 idle_timeout = 30 } } client localhost_ipv6 { ipv6addr = ::1 require_message_authenticator = no secret = <<< secret >>> limit { max_connections = 16 lifetime = 0 idle_timeout = 30 } } Debugger not attached #

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.
That's good.
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
That's bad.
I have been basically following these tutorials: * https://blog.svedr.in/posts/freeradius-peapv0+mschapv2-howto/
Which looks to be mostly copied from my site. How do you even find those pages? My site has been up for 15 years, and is pointed to from pretty much everywhere as the definitive guide.

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
See the Samba documentation for how their software works.
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: ... (1) mschap: ERROR: Program returned code (1) and output 'The attempted logon is invalid. This is either due to a bad username or authentication information. (0xc000006d)' (1) mschap: External script failed (1) mschap: ERROR: External script says: The attempted logon is invalid. This is either due to a bad username or authentication information. (0xc000006d) (1) mschap: ERROR: MS-CHAP2-Response is incorrect
That's pretty definitive. The ntlm_auth program is returning an error from Samba. No amount of poking FreeRADIUS will fix the problem. Unfortunately there is very little we can do here. If Samba is refusing to do ntlm, then you have to fix Samba. Alan DeKok.
Hi Alan, Thank you so much for pointing that out. I guess migrating to a new DC it is... All the best! On 2019-08-23 13:22, Alan DeKok wrote:

Hi there, I've solved it. Adding --allow-mschapv2 to /etc/freeradius/3.0/mods-enabled/mschap got the job done and now it's all working as it should. If anyone has the same problem in the future: ntlm_auth = "/usr/bin/ntlm_auth --allow-mschapv2 --request-nt-key --username=%{%{Stripped-User-Name}:-%{%{User-Name}:-None}} --challenge=%{%{mschap:Challenge}:-00} --nt-response=%{%{mschap:NT-Response}:-00}" All the best Oleg On 2019-08-23 13:41, Oleg Blyahher wrote:
