I was trying to setup user authentication via EAP with ACS server. what I did is just follow the configure of the url:http://www.cisco.com/en/US/products/hw/wireless/ps4570/products_configuration_example09186a00801bd035.shtml

Please check my AP configuration:

I am albe to telnet to the ACS server from AP, so there is no network reachability problem. can someone guide me how to reslove the problem?

thanks

try to check the logs of the RADIUS server for failed attempts, and the reasons those attempts failed. if no record, then there's communication issue between ACS and AP(check ACS's network configuration for AAA client as showed in the book), if have record, check related configuration accordingly, for example your global authentication setup,user/user group setup, client software config...
