OmniStack 6200 + EAP-MD5

[OXO-Man]

Hi @ all,
I´m trying to use a Window 2003 Server as a RADIUS-Server to authenticate the Login on my OmniPCX Enterprise and open the ports on my OmniStack 6200 (with an IPTouch 4068EE conneced).

I´ll tested the config with the "Steel belted Radius" and it works fine. If the IPTouch send it´s Login (via MD5) the OmniStack asks the Steel belted Radius and opens the port.

But if I configurate the IAS on my windows 2003 server as Radius-Server and use an Active Directory-User on my IPTouch, the Radius-Server replies with an "Reject".

Does anybody have a documentation about the configuration of the Windows 2003 Server as an IAS?

Thank you!
Best regards
