Hi i have problems again with authentication , i trying to use
freeradius and cisco 802.1x.
Windows said authentication error.
This is my users file:

xxxx   Cleartext-Password := "PPPPPl"
           Service-Type = NAS-Prompt-User,
           cisco-avpair = "shell:priv-lvl=15"

yyy     User-Password == "KKKK"

DEFAULT Auth-Type := Reject

I´m fallowing this doc
http://security.fi.infn.it/TRIP/802.1x-wired/802.1x-wired.html


This is my freeradius -X -A -d /etc/freeradius
