Aironet CB21AG-A-K9 and PEAP

[rdotson]

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.

Do you use CCKM? There is a known common misconfiguration. If you configure CCKM on the AP, you need to configure WPA->LEAP on ADU, not 802.1x->LEAP. Please go to the following URL:

If you are not using CCKM, please post the AP configuration and run the debugs as in the following URL:
