[Chilli] Auto login (bypass login form)

[Tsakiridis Sotiris]

  I've setup coovachilli - freeradius and works fine.

I wan't to give access to users without authentication. Just to land on 
welcome page and consider authondicated.
Is it possible to accomplise that? In other words, is it possible to 
have a predifined username and password into freeradius and force each 
new user, after he get an ip from coovachilli to automatically 
authondicated by these credentials without a login form?

Thanks in advanced!
