Linksys WRT54G - DD-WRT - Wireless Auth

[Richard Hamilton-Frost]

Hi there,

I'm new to Freeradius and have been bashing my head against this for
the last week now, I've read the FAQ and now feel really silly not
being able to work this out.

Specs:

RedHat 9 server (yes - I know prehistoric)
Linksys WRT54GL router, running DD-WRT (embedded Linux OS)
Freeradius version 1.1.4 (compiled from source)
Windows/OSX clients.

What I want:

To be able to authenticate wireless users via the /etc/passwd and
/etc/shadow files. I've setup the WRT54GL to talk to the Radius
server, this all seems fine and dandy. The WRT54GL is using WPA TKIP,
it has the option of WPA AES too, and WPA AES+TKIP, neither seem to
work.. here is the output I get when trying to authenticate a user:

I've read the FAQ and am now really stuck, anyone please please come to my aid!
