Hostapd working with unencrypted network, but not with encryption

[Morten W. Petersen]

Hi there.

I'm running hostapd on Raspbian, and can't seem to quite figure out
how to get authentication working.

When I setup hostapd to run an unencrypted network, things are fine,
but when I set wpa=2, wpa=1 - the clients accessing the AP show an
"authentication problem".

The output from running Hostapd is:

And I'm running Debian package hostapd version
