FreeRadius 2.1.3 authentication problem with passwd module

[bastardinho69]

Hi,

i want to authenticate users against a file similar to /etc/passwd file 
with passwd module. I have been reading the forums for some time but i 
cannot find out how to do it properly. I think i am loading that file in 
a wrong place in radiusd.conf file. I saw it must be called in authorize 
section but i cannot find such a section in my radiusd.conf file. When i 
call that  file in instantiate section in debugging mode server says 
that passwd module has loaded my file but server just doesnt check user 
names against my file.

Any help will be appreciated!
