Will there be a warning or error message in the syslog if the user certificate is expired?

If the CA cert is expired, will see a message like the following in the log on the WB45N:

Oct 15 13:38:35 summit user.info laird[303]: Event: SDC_E_CONNECTION_STATE status: AUTH_ERROR Oct 15 13:38:35 summit user.info laird[303]: Auth reason: INVALID_CREDENTIALS With an expired user cert, the EAP-TLS or PEAP-TLS authentication will fail.

The message shown above will show up in the log when authentication fails due to using an expired user certificate.
