Hi,

I don't remember exactly what I did on version 1. Please see:
http://vuksan.com/linux/dot1x/802-1x-LDAP.html
for some hints.

I had something like

DEFAULT Auth-Type .= LDAP
	Reply-Message = "Auth by LADP"

in my users file. Other attributes stored in an object of objectClass 
radiusprofile should be added automatically to the Reply attributes.

It is much simpler in verison 2 of FreeRADIUS. It nearly works out of the box. 
Just uncomment the ldap part in authorization and authentication sections.

Greetings,
