Hi, after I fully crashed my freeRADIUS Server I have to ask again: It still fails with: # Executing group from file /etc/freeradius/sites-enabled/inner-tunnel +- entering group authenticate {...} [eap] Request found, released from the list [eap] EAP/mschapv2 [eap] processing type mschapv2 [mschapv2] # Executing group from file /etc/freeradius/sites-enabled/inner-tunnel [mschapv2] +- entering group MS-CHAP {...} [mschap] Creating challenge hash with username: hausmeister@OBLAN [mschap] Told to do MS-CHAPv2 for hausmeister@OBLAN with NT-Password [mschap] expand: %{Stripped-User-Name} -> hausmeister [mschap] expand: --username=%{%{Stripped-User-Name}:-%{%{User-Name}:-None}} -> --username=hausmeister [mschap] Creating challenge hash with username: hausmeister@OBLAN [mschap] expand: %{mschap:Challenge} -> 01b99ad5745936be [mschap] expand: --challenge=%{%{mschap:Challenge}:-00} -> --challenge=01b99ad5745936be [mschap] expand: %{mschap:NT-Response} -> cfebe53922a2a18a8e0f423e8562a651148d2b18cd4fbc3e [mschap] expand: --nt-response=%{%{mschap:NT-Response}:-00} -> --nt- response=cfebe53922a2a18a8e0f423e8562a651148d2b18cd4fbc3e Exec-Program output: Reading winbind reply failed!

[mschap] FAILED: MS-CHAP2-Response is incorrect ++[mschap] returns reject so Im not sure why. I think its because hes not allowed to execute the ntlm or my mschap is cofigured wrong. (or both) I checked the users/groups: sambashare:x:111:haus-meister winbindd_priv:x:112:freerad freerad:x:113:freerad ssl-cert:x:114:freerad looks fine to me? So my NTLM_Auth string in the modules/mschap is: ntlm_auth = "/usr/bin/ntlm_auth --request-nt-key --username=%{%{Stripped-User-Name}:-%{%{User-Name}:-None}} --challenge=%{%{mschap:Challenge}:-00} --nt-response=%{%{mschap:NT-Response}:-00}" I allso tried a lot of other stuff nothing change. Hope you can help me again. -- Mit freundlichem Gruß Nicolas Fischer email: nfischer@hush.com jabber: jagger@jabber.ccc.de tel: 01573-0420888 Skype: jagger64 TOX: Just ask me :) PGP-Key: http://keyserver.ubuntu.com/pks/lookup?op=vindex&fingerprint=on&search=0xCF5...
