(RADIATOR) Mac OS X, MD5 and no internet access

[Oliver Jeckel]

Hi list,

I am evaluating the Radiator software and have difficulties with some  
eap-methods and hope some of you have an idea. I am using Mac OS X  
10.4.6 on a PowerBook G4 as a supplicant, Airport Extreme Basestation  
as an authenticator, and the Radiator software on Mac OS X 10.4.6  
configured for eap-md5.

Here is what happens:

I connect to the wlan using Internet Connect. When it comes to the  
authentication part, everything looks good – radiator in debug mode  
tells me that the access has been accepted and also Internet Connect  
tells me that I am connected to the wlan with md5. The only things  
which does not work is accessing the internet. I do not have an  
airport signal in the menu bar, nor does my PowerBook has a valid ip- 
address (it does have a self-signed though).
The same happens if I try to use eap-peap. Same results.

I know that the latter requires valid certificates on the client. The  
funny thing is that other authentication methods work as they should  
(eap-tls, eap-ttls). I even got authetication against the LDAP server  
of my Mac OS X Server working.

I know MD5 is probably not mentioned to be secure anylonger, but Peap  
is. And I am curious why it won't work.

Anyone?
