We succeeded to setup a Wireless LAN comprising: a 4404 Controller, 20 Access Points 1140 and an IAS server installed on Domain Controller
Each wireless machine with a personal certificate (issued to the computer account) authenticates (PEAP authentication with MS Radius Server for 802.1x) priory to the user authentication ( using Domain credential). Since one week, machines without a personal certificate are granted access to the wireless network. We cannot find out what have caused this change? Our aim is to grant access only to machines with personal certificate.
Please can you help
