Right, so you understand how the standard challenge response scheme works ?

1. generate random string
2. send random string as challenge
3. response = md5(challenge + passphrase)
4. send response
5. md5(challenge + passphrase) == response ?
(though if I remember correctly it's slightly more complicated)

So you need cleartext password both user side and server side , else it's not going to work.

so you need to get the cleartext passphrase into the server and associate it with the user.

In ldap it would be held in the attribute UserPassword,
in sql you would add into check items Cleartext-Password := passphrase
In the users file
user    Cleartext-Password := passphrase

Hi,
I'm building a radiusd client using libradius and trying to get
eap-md5 authentication
working.  My code sends a radius request with a user name, and an
eap message with
the username.
I receive a challenge from radiusd.  I return the challenge
response, md5(id,passwd,challenge), and radius state variable
but time out waiting for authentication.
The output from radiusd indicates "rlm_eap_md5 : Password is
required for EAP-MD5 Authentication".
When I add the password to the users file, I no longer receive
the challenge and timeout earlier.  Where is radiusd supposed to
get the passwd, and in what format ?


Cleartext for md5 challenge, and from any authentication source you wish
... sql , ldap , users file.
I don't follow.  Where does the cleartext go ?  I tried including the password in
the radius user password type.  The eap-md5 response is md5 hash.
