The authenticated identity needs to be sent by the AAA server to the IKE
responder in some cases only. For example, in EAP-SIM/AKA people often use
“temporary” (anonymized) identities in IDi. But in other cases, like
EAP-MSCHAPv2 or (God forbid!) EAP-GTC, there’s no need for a separate
“authenticated identity”. In these cases the IKE responder should simply use
the original IDi for policy lookup.

Hi Paul,

-------------------------------------------
When the initiator authentication uses EAP, it is possible that the
contents of the IDi payload is used only for AAA routing purposes and
selecting which EAP method to use. This value may be different from
the identity authenticated by the EAP method. It is important that
policy lookups and access control decisions use the actual
authenticated identity. Often the EAP server is implemented in a
separate AAA server that communicates with the IKEv2 responder. In
this case, the authenticated identity has to be sent from the AAA
server to the IKEv2 responder.

It says the autheticated EAP identity "has to" be send from AAA server, our
iterpretation is "has to" is obvious MUST.
I believe that is correct.
If AAA doesn't send the authenticated EAP identity, what should be the behavior?
I would assume "everything stops"
Also, what if AAA server EAP server is not AAA server?
Good question.
Can i open a ticket for it?
Yes, please!
