You seem to have disabled all authentication algorithms. In practice,
this means that no one is able to use your AP.. I should probably just
change hostapd to reject that kind of configuration. Anyway, auth_algs
is a bit field and it should be set to 1 (i.e., bit0 set) to allow Open
System Authentication when using IEEE 802.1X. Other possible values are
2 (only Shared Key Auth) and 3 (both Open System and Shared Key
accepted), but these should not be used with IEEE 802.1X.
