Help me configure freeradius

[thgjerde]

This is what i whant to do:

I have a wireless AP and and a linux server connected with a cat5 cable.
I then have a number of diffrenet wireless users that should be able to 
talk to the linux server
But they should not be able to listen in on each other.
they should not need a password or certificates

So what i was thinking about was to get freeradius to just allow all 
users to connect without checking for passwords and such.

Any tips on how to do this?
