Even though this service is commonly used by companies, there is a severe lack of support for WPA2-Enterprise. The functionality should support all of the following:
* Authentication with certificate.
* Authentication with username and password.
* Allow automatic renewal of certificate.
* Insecure authentication which ignore lack of certification.
Currently this has to be done manually which is really risky, as soon as you use the integrated web functionality, it will overwrite all previous settings, setting the RPi in a state which forces manual configuration by hardware retrieval.
