I wouldn't be surprised if pre-authentication would not work when
associated with a WPA-PSK AP. This is somewhat odd configuration of RSN
pre-authentication. I don't remember whether this is even allowed in the
IEEE 802.11 standard. Anyway, it looks like the problem here could be in
use of different SSIDs. I've only ever heard of pre-authentication used
within the same ESS, i.e., between APs that use the the same SSID.

Is this kind of network really deployed somewhere or is this just a test
case?
