Freeradius and Active directory

Hi.

What am I trying to do:
I would like to authenticate my Windows XP wireless clients against
Active Directory server via Freeradius.

What do I have:
I'm using freeradius 1.1.6 (installed via emerge) on Gentoo, Windows XP Pro

What works:
[WinXP]-->[freeradius]-->[w2003server]
1.)I'm able to send requests from Windows XP to freeradius (using
NTradping). (In an earlier testing phase I was able to authenticate
against "radius users file")
2.)I'm able to authenticate against AD (ntlm_auth).

What doesn't work:
When I try to bind phase 1.) and 2.) (ie. send request from winXP to
radius and let radius to authenticate against AD), it returns:

I see the problem in "No authenticate method...", but have no idea how
to repair it:(

Here is radiusd log:

I know there is something rotten in my configuration files, but can't
find it.
Thanks for any advice
