basic freeradius problem

my problem is really very simple :-)

System authentication doesn't work !

radius starts
it loads the unix module:

Module: Loaded System
unix: cache = no
unix: passwd = "/etc/passwd"
unix: shadow = "/etc/shadow"
unix: group = "/etc/group" <--- I had to enter these filenames in radiusd.conf !!!
unix: radwtmp = "/var/log/radius/radwtmp"
unix: usegroup = no
unix: cache_reload = 600
Module: Instantiated unix (unix)

"users" file without any changes
so every user matches default and gets System authenticated
"clients.conf" also with no changes, with localhost and testing123 password

however, when I try to do radtest I get an Access-reject

it works, when I put mu username and password in users file
like this:
xhon Password == "password"
Reply-message = "hello"

I have exactly the same configuration on my laptop (fedora 4)
and it works :-(

anyone ? it must some stupid mistake ..

--------------------------
rlm_unix reports "invalid password"
but the password is correct

another question: why NAS-IP-Address = 255.255.255.255 ?
why it is not localhost ip address ?

freeradius had to be started as root
http://marc.theaimsgroup.com/?l=freeradius-users&m=108973709319786&w=2

I don't know why. It works as dedicated radiusd user on fedora :-/
I prefer not to run it with root privileges, so if anyone can suggest anything....

Indeed a good question.
I'm stuck with the same problem and I see two possible solutions this far:
- either change ownershop of /etc/shadow (I don't really want to do this...)
- use PAM (which I can't get to work...)

Wuahahaha, forget that lastone...
I've tried half of the afternoon to get it working. And I found out that PAM works under two conditions:

1) start radiusd as a non-privileged user and use the following /etc/pam.d/radiusd
