Hi Help again please! I've read the doc at http://deployingradius.com/documents/configuration/active_directory.html and I'm now confused again. I'm running version 2.1.7 so module configurations are now in a separate directory rather than modules.conf. I have an access request packet containing User-name and User-Password. Where do I configure the ntlm_auth command so I can authenticate against Active Directory (which, by the way, is giving me more pain than anything else I've dealt with for quite a while!!)
