In this case it's a bit trickier.  Authentication will appear to succeed and the MPPE keys will look valid,  but wpa_supplicant/eapol_test will derive different values and report a mismatch.

You can't really verify correct behaviour just from the RADIUS server logs, you need to test with eapol_test/wpa_supplicant or get debugging logs which have the output of wpa_supplicant, off of the android device.
