Hi,

Hi,
I can't still figure it out why I can't access from Linux clients.
I use version 1.1.7 of freeradius. Linux client is a Fedora 8 system.
what is the linux client config?
i see the following in your debug
rlm_eap: Request found, released from the list
  rlm_eap: EAP/md5
  rlm_eap: processing type md5
rlm_eap_md5: User-Password is required for EAP-MD5 authentication
 rlm_eap: Handler failed in EAP/md5
  rlm_eap: Failed in EAP select
  modcall[authenticate]: module "eap" returns invalid for request 84
modcall: leaving group authenticate (returns invalid) for request 84
auth: Failed to validate the user.
i would also advise that you upgrade to 2.0.0 - not only could this
issue be resolves anyway - its a hell of a lof easier to debug - far
less EAP messages!

Well, Finally I get the blessed "Access-Accept" for Linux clients too.
How I did that? Well, I upgraded to radius 2.0.1.

maybe it could be helpful for many people my settings, well I won't
hide as alchemy secret ;)
