Here’s your problem: ntlm_auth = "/etc/freeradius/modules/ntlm_auth --request-nt-key --domain=OBLAN --username==%{%{User-Name}:-None}}" You have to set ntlm_auth to the path of the ntlm_auth binary… not the FreeRADIUS module. It usually lives in /usr/bin. ‘which ntlm_auth’ usually tells you where.

I have a problem with the auth against an Active Directory. I would be very thankfull if you could help me. Im tring to setup an WiFi Network where the Useres can auth with their AD Useraccs, Setup: WiFi-Router with DD-WRT Ubuntu 10.04LTS with FreeRADIUS kerberus samba etc. AD at a Windows Server 2008 SBS (Total mess never install it!) The communicatuion W-Lan Client->Router->FreeRADIUS runs. The Ubuntu Server is in the Domain, wbinfo -u gives me all Users. The auth via NTLM_AUTH runns too: /etc/freeradius$ ntlm_auth --request-nt-key --domain=DOMAINNAME --username=USERNAME Password: NT_STATUS_OK: Success (0x0) I think just FreeRADIUS is configured wrong. The auth fails, respectively does not take place. I put the config files and the freeradius -X output in the attachment. (I removed a few unimportant configfiles to not hit the 100kb limit of this mailinglist.) Many thanks in advance! -- Mit freundlichem Gruß Nicolas Fischer email: nfischer@hush.com<mailto:nfischer@hush.com> jabber: jagger@jabber.ccc.de<mailto: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...
