Hi,

I´m really going crazy with freeradius. I want to setup a working freeradius
proxy. Well, everything should have been configured correctly. I have my
certificates, I have installed everything, so freeradius tells me no more
errors when starting.

Well, what do I want?

- External users should be able to login on WLAN via 802.1X with
MSCHAPv2/PEAP in Windows XP.

When using local radtest to verify the user, everything looks okay. But as
soon I take a windows client, properly configured, or the radeapclient, it
doesn´t work.

Here is the output from radius -X.
It is 1.1.7, but the same errors occur on version 2.0.5:
There are two different requests. On (working) with local radtest, the other
one with radeapclient.
