Connection/disconnection problems with wpa_supplicant and hostapd when using WPA2 encryption

Dear Johannes,
I have added in attachment the hostapd log.
But the only thing I see is that the client (mac 00:23:a7:39:d0:69)
"did not acknowledge authentication" and that this causes the
disassociation.
What is the signification of the "reason_code=3" for the disassociation?
Thanks in advance for your help.
Best regards
