How to configure devices in order to log in with a username and password before a connection is made to the wireless network

[TCC_2]

Resolution

In the Protected Extensible Authentication Protocol (PEAP) MsChap V2, it is possible to configure two-password sign on as well as two usernames and passwords. You must have one set for Microsoft Windows and another for WLAN, but the WLAN username and passwords must be created under the Cisco Secure Access Control Software (ACS).

Refer to these documents for more information:
