["shrikant Bhat" <shrikabhat@gmail.com>]

Hi,
I am trying to integrate freeradius with ADS 2003. I reffred to 
http://deployingradius.com/documents/configuration/active_directory.html
. everything works perfectly fine till (
$ ntlm_auth --request-nt-key --domain=MYDOMAIN --username=user --password=password) I get NT_STATUS_OK. I dont see NT_KEY output. I made changes to  exec module in radius.conf as per the instructions, but radtest fails with Access-Reject .I have attached the debug window output for reference.
