In case it matters, we are using eap-aka with usim.

I instrumented the code, and it fails the eap->method test
(method is 23).

static int nai_realm_cred_username(struct nai_realm_eap *eap, struct wpa_supplicant *wpa_s)
	if (eap_get_name(EAP_VENDOR_IETF, eap->method) == NULL) {
		wpa_msg(wpa_s, MSG_DEBUG,
			"nai-realm-cred-username: EAP method not supported: %d",
		return 0; /* method not supported */

	if (eap->method != EAP_TYPE_TTLS && eap->method != EAP_TYPE_PEAP &&
	    eap->method != EAP_TYPE_FAST) {
		/* Only tunneled methods with username/password supported */
		wpa_msg(wpa_s, MSG_DEBUG,
			"nai-realm-cred-username:  Method: %d is not TTLS, PEAP or FAST.",
		return 0;

Any idea what needs to be done to get this working?
