I'm about to add this to eapol_test:
('eapol_test: Check EAP-Key-Name'). However, while implementing that,
I could not find where the format used by FreeRADIUS for EAP-Key-Name
("0x<hexstring>") is defined.
RFC 4072 defined EAP-Key-Name AVP as an OctetString and allocated a
RADIUS attribute type 102 for it. RFC 5247 has a pointer to that with
an indication that it can be used with RADIUS.
draft-ietf-radext-ieee802ext-12 calls this a "string" field (with RFC
2865 meaning of string being binary data). As such, I would have
expected to receive binary data, not a text string that has "0x"
prefix followed by a hexstring encoding of that binary data. Where
does this hex format come from? ACS?
Please also note that draft-ietf-radext-ieee802ext-12 adds this: "In
addition, the RADIUS server SHOULD include this Attribute in an
Access-Accept or CoA-Request only if an EAP-Key-Name Attribute was
present in the Access-Request." which does not match the current
