This is the last thing you want to do.  The consequence is that
any device that has a cert signed by that CA will be authorized
to use your network.

If you're too lazy to install the certs, you're better off
dropping EAP-TLS (which I assume is what you're trying to do) altogether
and going for something username/password based instead.
