Thanks for the update. The attribute contents look correct now.

I was wondering why it does still not get the identity, and took a
better look at the code. The identity with EAP protocols is actually
taken from EAP message that has type Identity (1).

For example the first EAP tunnelled request has this when testing with

        EAP-Message = <2><5><0><4><1>hvn

0x2 = Code (Response)
0x5 = Identifier
0x0004 = Lenght
0x1 = Type (Identity)
hvn = Type-Data

So you should check the logs to see if the client sends or gets prompted
and then sends its identity with a message like above.

Hmm, I think I have used Ubuntu 10.04 successfully with PEAP. But the
log should show what happens.

It might be a good idea to update to get access to all fixes and
enhancements, but I think it should work correctly with 4.3.1.
