Although Jans Auth Server has a session_id for each person who has authenticated, applications generally have their own sessions. Upon logout from an OpenID Provider, ideally all RPs are notified, so they can also their local sessions. The OpenID solution to implement logout is currently described in the OpenID Connect Front Channel Logout specification.

In practice, here's how it works:

  • Jans Auth Server end_session endpoint returns an HTML page, which contains an iFrame for each application to which the user has authenticated.
  • The iFrame contains a link to each application's respective logout URL.
  • The special HTML page should be loaded in the background and not displayed to the user.
  • The iFrame URLs should be loaded by the browser.
  • Now, upon logout, the user is calling the logout page of each application, the local cookies are cleared, and the user is signed out of all applications.
