Returns the boolean value of whether or not the
RADIUS library should trust all server certificates
or should validate them against known CA certificates,
as configured in guacamole.properties.  By default
this is false, indicating that server certificates
must be validated against a known good CA.

@return
    True if the RADIUS client should trust all
    server certificates; false if it should
    validate against known good CA certificates.

@throws GuacamoleException
    If guacamole.properties cannot be parsed.
