You are right it works also with configuration 0 but I get a warning that the
driver couldn't configured in manged mode. This is clear because I configure
the driver in IBSS mode.

Sure, I try to implement WPA2-PSK for IBSS mode. For this I modified hostapd
and wpa_supplicant that they run in IBSS mode. Also I have already changed
some parts in the madwifi driver. Now the 4-way-handshake works in one
direction and I can transmit and receive encrypted data between two adhoc
stations. On one station I start hostapd which I have already modified so that
I add a new start command flag to start it in adhoc mode.
Now I have a problem with bssid of the state machine in wpa_supplicant. Sometimes
there is only 00:00:00:00:00:00 as bssid so I make a hack in 
wpa_supplicant_process_1_of_4() which copy the src_addr in the bssid. Otherwise
the 4-way-handshake don't work in IBSS mode but with this hack it works for now.
The hack is not for INFRA mode so I have to make a decision if IBSS is selected or not.
Or have you an idea what can be go wrong with the bssid in IBSS mode?
The function wpa_driver_wext_get_bssid() return the correct bssid.

If this works the next step I have to do is to run hostapd and wpa_supplicant in
one process like test_wpa it already shows but with working 4-way-handshake
in one direction such it is now with separately hostapd and wpa_supplicant.
If this works the next steps I have to do are descibed in the standard and you
also wrote some notes in other posts.
So if you have some hints for me it will be nice!
