Windows XP hangs forever during PEAP auth on freeradius with winbind/AD backend

Hello all,
I've been at this for two full days with no luck so I hope that folks
here will take me under their wing. :->
I am trying to setup freeradius so that hosts running windows XP/SP2
can be authenticated via .1x. when plugged in to a 3Com 3226 switch.
The freeradius server version is 2.1.4, built from source, I added SSL
libraries since Debian's deb for freeradius doesn't ship with them. My
server is running Debian Lenny.
I am using winbind to provide authentication services to Windows AD 2003/sp2.
I am following the directions posted on the freeradius wiki (which is
a bit out of date btw)
http://wiki.freeradius.org/FreeRADIUS_Active_Directory_Integration_HOWTO
I can list domain users via wbinfo -u and getent passwd.
and doing
wbinfo -a raduser%testing123 yields
plaintext password authentication succeeded
challenge/response password authentication succeeded
ntlm_auth --request-nt-key --domain=VANGUARD --username=raduser
password:
NT_STATUS_OK: Success (0x0)
However doing radtest fails, but read on before you jump to conclusions...
radtest raduser testing123 localhost 0 testing123
Sending Access-Request of id 144 to 127.0.0.1 port 1812
User-Name = "raduser"
User-Password = "testing123"
NAS-IP-Address = 10.1.1.51
NAS-Port = 0
rad_recv: Access-Reject packet from host 127.0.0.1 port 1812, id=144, length=20
I believe my problem resembles the description on the FAQ re: windows machines
http://wiki.freeradius.org/index.php/FAQ#PEAP_or_EAP-TLS_Doesn.27t_Work_with_a_Windows_machine
I have patched the windows client per the instructions but no dice.
I read the link http://support.microsoft.com/kb/814394/en-us but it is
my understanding that freeradius supports winxp crafted certificates
(via certs/xpextensions) out of the box when it builds the example
certs in /etc/freeradius/certs so I am not sure what to do here
Wireshark shows me that after the windows machine is plugged into my
3com switch on a port which is configured for radius that the windows
client makes an Access-Request and receives and Access-Challenge. This
happen twice and then nothing....
I'd appreciate any guidance folks could give me!
Thanks!
John
