Review of Second Proposed Errata Set for OpenID Connect Specifications

Published October 21, 2023

The OpenID Connect Working Group recommends the approval of Errata corrections to the following specifications:

An Errata version of a specification incorporates corrections identified after the Final Specification was published. This would be the second set of errata corrections for Core, Discovery, and Dynamic Client Registration and the first Back-Channel Logout. This note starts the 45 day public review period for the specification drafts in accordance with the OpenID Foundation IPR policies and procedures. This review period will end on Tuesday, December 5, 2023. Unless issues are identified during the review that the working group believes must be addressed by revising the drafts, this review period will be followed by a seven day voting period during which OpenID Foundation members will vote on whether to approve these drafts as OpenID Errata Specifications. For the convenience of members who have completed their reviews by then, voting will actually open a week early on Wednesday, November 29, 2023, with the voting period still ending on Wednesday, December 13, 2023. The specifications incorporating the proposed Errata corrections are available at:
