Welcome

Discussion on issue "SP supporting CIBA with two IDPs: B2B/B2C" #141

Nicholas Manolakos https://github.com/questsin

Discussion on issue "More than one "purpose" in an authorization request. #140"

Elisabeth Mueller 

Axel: We see that there might be UX issues if a clients needs to ask for multiple purposes but we got no business requirement from anybody.

After a long discussion we seem agree that the keep the basic idea to have a request-parameter `purpose`.

Axel proposed a wording change:

Purpose

An OPTIONAL transaction specific request parameter purpose as specified in openid-connect-4-identity-assurance-1_0-13 allows the client to state the purpose of the requested scopes.

The purpose string MUST use below format for interoperability

dpv:<dpvValue>

<dpvValue> is coming from W3C DPV purpose definition

Axel asked the group to approve that text and to close issue #140

Proposal to set a deadline to give feedback stating a business need to go for option 2. Otherwise ICM goes for Option 1.

Axel will raise that again at tomorrows TSC meeting.

Elisabeth Mueller proposed that TEF proposes some text regarding existing implementations. Jesús Peña García-Oliva takes the AP to propose a disclaimer text in PR #121

Discussion about Terms like SHALL, SHOULD, etc

Bjorn Hjelm asked why the document does not use the term "SHALL" in one particular sentence.

Axel answered that he prefers to phrase requirements using the term "MUST" or "REQUIRE" instead of "SHALL".

Discussion on "openid" missing in scope

TEF agrees that the openid scope is listed as required in the standard, but it does not specify a behavior in case it is not sent. In CAMARA profile, a behavior is being established (returning invalid_request) that TEF believes it could impact on implementations where OAuth2 and OIDC solutions coexist.

Discussion on issue  "Clarify role and usage of id token #136"

Elisabeth Mueller 

Jesús Peña García-Oliva refers to his comment in this issue as TEF position on the matter. 

Discussion on issue "Clarification needed for login_hint, login_hint_token and id_token_hint #133"

Former user (Deleted) 

Jesús Peña García-Oliva commented on the issue: So the current PR content is already fine. We may be able to close this issue then.

Jesús clarifies that TEF is happy to close the issue as long as the WG agrees to document only the login_hint option in PR #121 context, which is what there was consensus for. And as long as the existing text in the OIDC profile is clear and consistent.
After discussing it, it is proposed to rephrase the text in PR #121 to make it clearer. Jesús Peña García-Oliva takes the AP to do it.

Discussion on "Proposal to define a strict value for aud claim in the private_key_jwt #127"

Ming Hui Foo 

Propose to only allow a single value for aud claim and the aud claim value has to be the endpoint of the API invocation.

TEF propose to be is aligned with CIBA and FAPI standards as commented in the issue.
