EAP-AKA set-up failure on 4.0 dev. stream

[yukou katori]

I'm setting up EAP-AKA on 4.0 dev. stream, because I have to set up EAP-AKA.

I got the following error.

Radiusd -X

/// snip ///

talloc_bstrndup(eap_aka_session, inst->network_id,
./rlm_eap_aka.c: talloc_array_length(inst->network_id) - 1);

It seems ""network_id" must have a value", what should I do for this error?

I know it's dev. stream, but any comment would be really appreciated to set
it up.

Regards,
