OK, I guess I am really confused now :)

There are two distinct cases:

* For services that are configured to logout in a back-channelish(!) way. In this case, the logout manager simply performs the job.

* For services that are configured to logout using front-channel, the logout manager does nothing but to only "collect" these requests and put them into the webflow, as you note. In this case, the log message of `Performing back channel logout...` is incorrect, because we are just gathering info here and not much else. Right?
