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.
