malformed RADIUS message when using IAS for 802.1x

[dengqi]

I'm trying to use Win2003 IAS for 802.1x authentication. But the event log of IAS keeps give me the error message"A malformed RADIUS message was received from client XXX. The data is the RADIUS message." I have checked that the radius key is correct. Anyone know what the problem is?

You might need to set some vendor-specific attributes in the matching remote access policy profile. Use the following URL for the radius attributes

Did you get any further with this? I am having the same problem.
