Subject: OpenID Connect Back-Channel Logout Specification

A new back-channel OpenID Connect Logout spec has been published at
http://openid.net/specs/openid-connect-backchannel-1_0.html.  This can coexist with or be used instead of the front-channel-based
Session Management and
HTTP-Based Logout specifications.
The abstract for the new specification states:
This specification defines a logout mechanism that uses back-channel communication between the OP and RPs being logged out; this differs from front-channel logout mechanisms, which communicate logout requests
 from the OP to RPs via the User Agent.
This completes publication of the three planned OpenID Connect logout mechanisms:  two that communicate on the front-channel through the User Agent (browser) and this one that communicates on the back-channel, without involving the User
 Agent.  See 
the Introduction for a discussion of the upsides and downsides of the different logout approaches.  As much as we'd like there to be a single logout solution, both experience and extensive discussions led us to the conclusion that there isn't a feasible
 one-size-fits-all approach.
Reviews of the new (and existing!) specifications are welcomed.
Thanks to John Bradley, Pedro Felix, Nat Sakimura, Brian Campbell, and Todd Lainhart for their contributions to the creation of the specification.
                                                            -- Mike
