I have seen in the forum that the Logout behaviour changed in Keycloak 18.00
(How is logout really working and can we bypass the logout-confirm page?)
According the discussion, and for the test I made, if I don’t use the post_redirect_uri parameter in the logout endpoint, no call is made to my app after a keycloak logout.
Though in the Admin interface, there is still a parameter Backchannel Logout URL (I didn’t managed to make it work, it is never called).
Does that mean that parameter is deprecated and not working ?
