Configuring PEAP on IAS with autonomous aps and getting the following error on the IAS serevr so I know that the ap is talking to the IAS.

Not sure what I am missing, is there some attribute I need to look at??

An Access-Request message was received from RADIUS client xxx.xxx.x.xxx with a message authenticator attribute that is not valid.

Also Windiws IAS should use port 1812? but I get no messages with port 1812 just port 1645?

Any help appreciated.

I got the message with a switch..a ios update fixed the problem.

The IAS works on both, 1812 and 1645 and you are able to fix it on both sides (AP and IAS) if you want...

Did you configure Cisco as vendor in the ias client config?
