You have to install a self-generated certificate on the ACS, and enabled PEAP with "Allow EAP-MSCHAPv2". then changed the setting on our PC, and manage to make it work.
Could you do the following,
1.) Enable full detail logging on the ACS: System Configuration -> Service
Control -> Logging detail level = "FULL". Then restart the ACS services.
2.) Enable "debug radius" together with the debugs that you already have
on the switch
3.) If there is a sniffer (Norton SnifferPro, or the freeware Wireshark or
Ethereal) on the client laptop, please start it and enable sniffing on the
client interface.
4.) Make another authentication attempt.
5.) Generate a "package.cab" on the ACS, by running Bin\CSSupport.exe
underneath the ACS installation directory
6.) Please send me the following information,
a) The package.cab file,
b) the debug output from the switch,
c) the sniffer trace (if available).
