What areas are you referering to? Because there should be some front-channel SLO process if the UI is involved.

When the /logout url is called, the logout-webflow.xml is called and services which were marked as "Front channel" will be processed accordingly.

Every time we perform logout, we should call the ```destroyTicketGrantingTicket``` method but also process the front channel logout requests whenever it's possible. I think it's the case here...
