I'm setting up a WLAN using Cisco AP1231G-A-K9 access points. I'm using Cisco ACS 3.3 for 802.1x Radius authentication and authenticating using Active Directory.
I have Dell Wireless and Cisco Aironet 350 client adapters working perfectly, but I'm having a problem with the Aironet a/b/g cards. They connect to the AP, but will not authenitcate. I've tried several different versions of the ACU. The error in ACS is:
EAP-TLS or PEAP authentication failed during SSL handshake.
Any help would be appreciated.
