This Consultation is now CLOSED. A post consultation version of the proposal is now with the REFEDS Steering Committee for consideration.


The Seamless Access Entity Categories and Attribute Bundles Working Group has approached REFEDS and asked if it will become the custodians of a proposed new Entity Category: "Pseudonymous Authorization".  As per the REFEDS Consultations guidelines, the REFEDS Steering Committee has reviewed and accepted that this proposal meets the criteria for a REFEDS Consultation. We are therefore opening up a consultation period to invite comments and questions from the REFEDS Community. 

Please note the proposed URI would be changed to a URI within the REFEDS domain space if this category is accepted.


This consultation was open from: Monday 6th July 2020 at 17:00 CEST to Monday 31st August at 17:00 CEST

Participants are invited to:

  • to consider the proposed entity category
  • propose appropriate changes / challenges to the propose text, and
  • confirm that they are happy that this should be considered as a REFEDS Entity Category. 

The document for the consultation is available as a Google doc in Suggestion mode or as a pdf attachment.  All comments should be made on:, added to the google doc as a suggestion or added to the change log below.  Comments posted to other lists will not be included in the consultation review.

As an editorial comment I'd suggest avoiding all the "For the purposes
of this document" re-definitions or existing terms and instead
referencing existing glossaries where possible. (No need to define
what attributes, users, affiliations, etc. are here, IMO.)

Supported in google doc comments

02general note that none of the 3 specs mentions NameIDs which are not
attributes (and so do not fall under the local -- and somewhat circual
-- definition of "user attributes": "a user attribute is *an*
*attribute* that [...]"; my emphasis) but are personal data and
suitable to identify the subject, in cooperation with the IDP, or even
without, depending on the NameID format, nonetheless.
So that seems like a significant omission

03lines 61, 62, generalAs mentioned also with "Authentication Only" comment 04, I do not see the added value of bringing in bilateral agreements. It only weakens the spec, and there is no need because bilateral agreements can always be made.Niels van Dijk, SURF
04line 92Why is the thing now called "Organizational identifier" as compared to the Anonymous Authorization specification where it is called "Organization". I would suggest to harmonize concepts between specficationsNiels van Dijk, SURF
05line 91 -93"Organisation identifier", especially if provided in the form of eduPersonScopedAffiliation, is in many cases already a very usefull and likely enough to manage authorization. What if the service has no need for additional roles/groups being provided via the currently required entitlement(s)?
I would suggest to state either Organizational or Entitlement MUST be provided, where both MAY be provided
Niels van Dijk, SURF
06line 105-106It is bad practice to send empty attribute statements, so how to combine the mandatory entitlement as per line 91 with the statement in these lines where it might be that no entitlement data is relevant to the SP? Also see (05)Niels van Dijk, SURF
07line 96.3Which schema does the memberOf attribute come from?Niels van Dijk, SURF
08line 111Given the aforementioned lack of support for pairwise user identifier, I would word this as "

Identity Providers are advised to add support for to the new pairwise identifiers as soon as practicable."

As that is much easier then waiting until all your connected SPs have migrated

09line 116Why not (very strongly) suggest  using edupersonentitlements for the purpose of metrics? While the value of ePTID needs to be commonly agreed upon by SP and IdP to be meaningful, now at least we can get away from inventing new attributes for metrics.Niels van Dijk, SURF
08line 130"when supported by their federation assert this in metadata" is that a MUST also? or perhaps a SHOULD?Niels van Dijk, SURF
09line 174Using normative wording in implementation guide conflics with normative wording in core document. I would suggest to remove RFC2119 wording from the implementation guide so it is clear that is not normative, but informative.Niels van Dijk, SURF
10line 253I am missing any wording on ePPN here. Is that on purpose?
eduPersonUniqueID has teh same propperties as the pairwise id.  Perhaps explain why that is not reccomended?
Niels van Dijk, SURF
11section 4 entitlement dataEntity categories are intended to facilitate scalable and preferably automated attribute release. eduPersonEntitlement, isMemberOf and MemberOf are attributes whose values should from a security perspective only should be presented to the intended services. Due to this the attribute release of these three attributes should be configured outside entity category release mechanism.Pål Axelsson, Sunet
