802.1x + freeradius authentication problem

[Ramon Barquier <Ramon.Barquier@uab.es>]

Hi all,

We are trying to set up an environment with 802.1x + Freeradius for our 
Wireless net. Our goal is to authenticate Windows XP clients using EAP.

Our radius server is bound to an LDAP database. We have tested our users 
with a "radius-test" tool and everything seems to work fine, but when 
trying to validate in our 802.1x environment, the radius server rejects 
the user. In fact, although we get a "authorize returns ok", there seems 
to be an additional check that claims the user has no password.

Any ideas? We attach the radiusd log (hope it helps!).

Thanks in advance,
