get_ca_cert_path

Returns the CA certificate path if the CA certificate is stored using the PATH scheme.

Not all EAP methods use a CA certificate (LEAP for example), and those that can take advantage of the CA certificate allow it to be unset. Note that lack of a CA certificate reduces security by allowing man-in-the-middle attacks, because the identity of the network cannot be confirmed by the client.

Parameters:

this	the Setting8021x

Returns:

path to the CA certificate file
