Have you used similar configuration before? As an example, WinXP SP2
started requiring wireless connections to be encrypted in order to even
allow IEEE 802.1X to be used in the first place. In addition, there are
client implementations that will refuse to associated with an AP if the
AP is configured to indicate in the beacon frames that it is using
encryption (which is needed for WinXP SP2 + IEEE 802.1X) if the client
is configured to use unencrypted connection. In other words, using a
single BSS for both of these uses may not work with all clients.
