Configuring FreeRADIUS to use ntlm_auth

[charles@copel.com]

Hi All:

My name is Charles and I am starting to use FreeRadius. I need to "Configure my FreeRadius to use ntlm_auth for MS-CHAP" to authenticate  NT users.

I am following the procedures about "Deploying Radius" and I am with problem in following the procedure about "Configuring FreeRADIUS to use ntlm_auth" described in the "http://deployingradius.com/documents/configuration/active_directory.html". 

After I configure the users file with  "user          Auth-Type := ntlm_auth" (for testing purposes only), my FreeRadius don´t start and show the followings errors:

/usr/local/etc/raddb/users[1]: Parse error (check) for entry user: Unknown value ntlm_auth for attribute Auth-Type
Errors reading /usr/local/etc/raddb/users
radiusd.conf[1074]: files: Module instantiation failed.
radiusd.conf[1859] Unknown module "files".
radiusd.conf[1795] Failed to parse authorize section.

My environment is: FreeBSD 6.2 + Samba 3.0.24 + freeradius 1.1.6 
My samba is ok I did the test that is described in the "Deploying Radius".

Any Idea ?
Thanks,
Charles.
