Freeradius and Active directory

[Tomás( Janec(ek]

Hi.

Because we can authenticate against AD only (not only, but...) using 
MS-CHAP, I had to extend the system to its final form (I don't know any 
MS-CHAP testing utility):

[WinXP] -> [AP] -> [FreeRadius] -> [AD server]
(ie. I'm using wireless interface in Windows to connect to AP and 
authenticate against AD)

Everything looks good. I can see the request from AP and authentication 
activities it entails between FreeRadius and AD. But the authentication 
is never successful.

This is the request in radiusd -X:

*********************************************************************

The problem I see is "Login incorrect: [user/<no User-Password 
attribute>]". It looks like Windows doesn't send user's password. I 
followed the supplicant configuration part from 
http://wiki.freeradius.org/FreeRADIUS_Active_Directory_Integration_HOWTO.

I know that this is not exactly FreeRadius question... Does anybody 
know, what is the problem, what to double check ... ?
