Your path to ntlm auth is wrong. You need to specify the path to the ntlm auth bin/exe that comes with samba. G -----Original Message----- From: freeradius-users-bounces+ggatten=waddell....@lists.freeradius.org [mailto:freeradius-users-bounces+ggatten=waddell....@lists.freeradius.org] On Behalf Of Edge Sent: Friday, July 15, 2011 9:27 AM To: freeradius-users@lists.freeradius.org Subject: Error with AD/freeradius config OK, sorry as this is a long mail because Im going to include as much config as possible. I have been playing around trying to get this to work with little success though the debug error messages have changed since yesterday Im having trouble getting freeradius to use ntlm_auth - the error massage is now stating a permission error.. Just to confirm, Im following the steps on deployingradius.com .. PAP has been tested and is working Samba configured and working wbinfo -a = works, having tested multiple logins ntlm_auth --request-nt-key --domain=MYDOMAIN --username=user --password=password = working, again tested with multiple logins radtest user password localhost 0 testing123 = does not work, see debug info at end of email.. Contents of/raddb/modules/ntlm_auth file # # For testing ntlm_auth authentication with PAP. # # If you have problems with authentication failing, even when the # password is good, it may be a bug in Samba: # # https://bugzilla.samba.org/show_bug.cgi?id=6563 # exec ntlm_auth { wait = yes program = "/usr/local/etc/raddb/modules/ntlm_auth --request-nt-key --domain=xxxxxxxxxx --username=%{mschap:User-Name} --password=%{User-Password}" } I have modified the authenticate sections of the raddb/sites-enabled/default file, and of the raddb/sites-enabled/inner-tunnel file Listed below are the authenticate sections only as that is all I have changed.... sites-enabled/default authenticate { # # PAP authentication, when a back-end database listed # in the 'authorize' section supplies a password.
