I'm not exactly sure that it does.  From your debug output, it looks
like it's not seeing any BSSIDs; it's going ahead and using the
"mydomain" SSID, but that doesn't mean it sees anything that matches the
rest of its configuration.

Doesn't the sample config file say that you have to specify one value
for all of:

key_mgmt
pairwise
group
proto

when you use ap_scan=2?  The defaults for all of these are multiple
values, I believe.  Your output makes it look like wpa_supplicant is
trying to use CCMP for both pairwise and group, and either RSN or WPA
for proto (I'm not exactly sure which).  Is your AP set up to do that?
Or is it set up to do WPA (version 1) with TKIP encryption instead?

(These lines are why I know it's using CCMP, and I think it's using
WPA.)

And it can't find a BSSID that matches its configuration (at least, I
think that's the problem); normally there's a nonzero BSSID shown.

If your AP is set to do WPA-PSK with TKIP (not CCMP/AES/WPA2/whatever),
then try adding:

pairwise=TKIP
group=TKIP
proto=WPA

to the network block.  Otherwise try adding:

pairwise=CCMP
group=CCMP
proto=RSN

to the network block.
