If your external server is a RADIUS server, yes it does. This is called RADIUS proxying : the server acts as a client for another RADIUS server. And does the external server send and ACCESS-ACCEPT with REPLY_MESSAGE information If authentication is successful? What your external server does and returns is up to its configuration. -- Alexandre Coninx - List info/subscribe/unsubscribe? See http://www.freeradius.org/list/users.html

Unfortunately, there is no integrated WPA supplicant in Windows 2000. You will have to use an external supplicant. Until now, i haven't found any free software doing that. There is a (proprietary) W2K WPA software available there : http://www.wirelesssecuritycorp.com/wsc/public/WPAAssistant.do . The basic version that does WPA-PSK is available at no cost (i didn't test it), but you must pay for the version with WPA-RADIUS support. -- Alexandre Coninx - List info/subscribe/unsubscribe?

I spent a little time figuring out the differences between the two formats and adapting FR's dictionnary.microsoft to be used by libradius ; you can get my adapted file at http://ramiel/~endy/dictionary.microsoft The format may depend of libradius'version, so i don't guarantee anything. It's really a pain that there is no standard format (yet ?) for dictionnary files. -- Alexandre Coninx - List info/subscribe/unsubscribe? See http://www.freeradius.org/list/users.html

Your ntlm_auth command line is incorrect : you only supply the username,
so ntlm_auth runs in interactive mode and asks you the password.
You should supply the Challenge and NT-Response attributes from the
EAP-MACHAPv2 packet too. Try to modify the mschap section of your
radiusd.conf by setting something like :
ntlm_auth = /usr/bin/ntlm_auth --request-nt-key

That is useless if you just want to authenticate by validating the
client SSL certificate.

eap {
peap {
default_eap_type = mschapv2
}
}
mschapv2 {
}
Your freeradius is configured to do PEAP MSCHAPv2 by default, and not
PEAP TLS. I suppose it's just a default behavior and it won't interfere
if the supplicant explicitely requests PEAP TLS, but maybe you should
disable the MSCHAP stuff and set default_eap_type = tls in the PEAP
section. It would make your config file cleaner, if nothing else.

I don'y know OpenSSL and its obscure error messages well, but it seems
to have a problem with your client certificate. If i were you, i would
check that the right certificate and authentication method are selected
in the client's configuration.

Why not just use Calling-Station-Id as a check item???
In fact, the logins and MAC addresses are in a postgreSQL database,
along with much other data about our users. I certainly could have used
the postgresql module (and i will probably try later), but i used an
external script partly out of lazyness, and partly because when a user
fails authorization, i want to do and log different things depending
on the cause of the failure (unknown MAC, MAC owned by another user,
disabled account, ...)

hi all,
i want to authenticate users at a cisco router by checking the

Hello,
I manage to do that by first checking the MAC during the authorization
process with an external script (using the exec module), and then
authenticating the user with user/password with wathever method you
want to use (in my case PEAP-MSCHAPv2 + ntlm_auth, but any other should
work).
My radiusd.conf looks like this :
modules {
...
exec mac_check {
wait = yes
program = /path/to/your/script.pl %{User-Name} %{Calling-Station-Id}
input_pairs = request
output_pairs = reply
packet_type = Access-Request
...
}
}
authorize {
preprocess
auth_log
mac_check
mschap
eap
}
authenticate {
Auth-Type MS-CHAP {
mschap
}
eap
}
The script is a simple perl script that connects to our members
database, checks if the MAC is registered and belongs to the
member trying to connect, and refuse (exit 1;) or accept (exit 0;)
authorization based on that.
There is probably a cleaner way to do that, but it works well.
