PEAP CA certificate error

[Jonathan <talljon84 yahoo com>]

Hello-

I'm attempting to connect to a PEAP and msCHAPv2 network using network manager 0.7 (openSUSE 11.1). The wpa_supplicant.log file is showing that the verification of the certificate is failing but I'm unclear how to overcome this.

The IS group has Windows machines not checking the validity of the certificate; I presume because it's broken or expired. Can anyone offer suggestions on how I can around the error on my Linux laptop and connect?

Many thanks in advance,
Jon
