Works fine for me with wpa_supplicant.. For example with this as an
extension to tests/hwsim/

def test_dbus_ap_simple(dev, apdev):
    """D-Bus AddNetwork for AP mode (simple)"""
    (bus,wpas_obj,path,if_obj) = prepare_dbus(dev[0])
    iface = dbus.Interface(if_obj, WPAS_DBUS_IFACE)

    ssid = "test-wpa2-psk"
    passphrase = 'qwertyuiop'
    args = dbus.Dictionary({ 'ssid': ssid,
                             'key_mgmt': 'WPA-PSK',
                             'psk': passphrase,
                             'mode': 2,
                             'frequency': 2412 },
    netw = iface.AddNetwork(args)

    dev[1].connect(ssid, psk=passphrase, scan_freq="2412")
