Hi folks,

I need develop a application that performs EAP-PEAP authentication. My
access
point is a Cisco AP1200 and my wireless card is a Cisco 350
series(running on
windows 2000 professional). My client program is being developed using
Visual C++ .NET

I am a beginner, therefore sorry if ask some inconsistencies. My
questions are:

1. Which configuration are required for support eap-peap? (Only client
side, the server is ok.)

2. Which protected eap (PEAP) dll must I use?
   I have tried rastls.dll(c:\winnt\system32\rastls.dll). Is that
correct?

3. What are the steps to start the authentication process?

   In my test I load the rastls.dll and called the following
functions:
   * RasEapGetInfo to recover PPP_EAP_INFO structure for the
authentication protocol
   * After that I call the function RasEapInitialize
   * And after RasEapBegin

   Is this procedure correct?

   Please explain me how the system works? How the messages are
exchanged? Who start
   the authentication? What is the relation between the Ndis driver
protocol and the EAP,
   I mean in which order they have to be used and which OIDs must be
configured before start
   the authentication. Could anyone send a diagram describing the
order of the
   functions should be called?

4. If I want use my own authentication interface, what should I do?

Thanks in advance,

Claudio.
