I have set up a windows RADIUS server to integrate with AD and have configured an AP1220 (v12.3(8)JEB) to authenticate a user logon thru EAP. It appears that I have the configuration correct on the AP and I can see the laptop showing as "association processing" thru the web interface of the AP. The laptop itself, tho, appears unable to authenticate and the wireless card reports "windows was unable to find a certificate to log you onto the network". What am I missing here? Thanks in advance for your replies.
