If your PEAP authentication fails, it may be due to many reasons including:
- An incorrect username and password on the RADIUS server.
- An incorrect PEAP configuration.
- You may be experiencing Cisco bug ID CSCee06008 where PEAP fails with Aironet Desktop Utility (ADU) version 1.2.0.4.
The workaround is to use the latest version of the ADU which is either version 2.5 or 2.6.
---------------------------
CSCee06008 Bug Details:
MS PEAP machine authentication does not work with the ADU supplicant.
Users without cached credentials cannot login to Windows Domain.
If the Microsoft-supplied 802.1x supplicant is used in XP SP1 or SP2, MS PEAP machine authentication works as expected and non-cached users are able to log into Windows Domain.
There is no workaround for Windows 2000 clients.
This problem is now resolved in the Install Wizard 1.3 release for CB21AG/PI21AG adapters, available from Cisco TAC:

Protected EAP (PEAP) is a draft EAP authentication type that is designed to allow hybrid authentication.
PEAP employs server-side Public Key Infrastructure (PKI) authentication.
For client-side authentication, PEAP can use any other EAP authentication type.
