Arnauld,
It almost looks like something in the supplicant is not configured properly
to use the certificate sent from the server during the handshake phase... I
have attached a copy of some of my notes (written to myself so some of the
"meaning" in the notes may not be exactly correct - but heck - they were for
me anyway [grin]) that show a EAP/TTLS session negotiation...
Take a look and compare to what you are doing to see if you can determine
where things are going off the deep end... I would suggest setting up
testing for EAP/TTLS in a simple configuration for user authorization
first - then fold in the Ldap authorization....
Hope this helps....
gm...

Radiusd debug output for successful connection using EAP/TTLS
---------------- Start of Debug output, items with *** are my notes to myself
--------------
NOTE: My interpratation of what is actually occuring may not be 100% correct but, heck,
these are notes to myself [grin]... nothing has been added or deleted to actual
output.
One thing to notice is the information sent to the radius server by the
supplicant
client does not actually send valid authorization request data until the TTLS
link has
been established and verified! Nice touch!!!

------------------------ end of debug text -------------------------
NOTES: Since EAP/TTLS is not dependent on the actual access authorization method I
chose to use
the easy method (basic authorization). Other forms of authorization such as
Ldap
or sql would only add layers and would not help in debugging any problems in
the
initial testing of the EAP/TTLS protocol method of connection. The use of
Ldap or
sql authorization will work just as well as the unix password or users file
authorization methods.
1. Each supplicant has it�s own set of transmission and reception keys for
the session. They are not shared with other supplicants on the same wireless
router.
2. The Radius Server is the only server which requires a security certificate �
it can
either be a commercial security certificate or a self-signed certificate created
locally.
3. The supplicant (client) device MUST use a wireless network interface device
that has current
WPA enabled hardware drivers.
4. The radius server is configured to use the unix password system for user
verification � this
will work with any of the user verification methods supported by the radius
server and eap/ttls�
5. Total time to establish the wireless link : Less than 2 seconds with the
equipment used for
testing.
� WRT54G Linksys Wireless Access Router running latest software
� Linksys wireless access PCMCIA network card with latest software WPA enabled
driver.
� Odyssey Supplicant software (came with the PCMCIA wireless network card).
� Freeradius version 1.X pre release
6. This file generated with a CVS version from Feb 2004, It may be 'dated' but the
method is
basically the same for eap/ttls operation.
