The IdP can fallback to back-channel, if the logout is front-channel and the SP software does support only back-channel bindings. '''Not the other way''', because front-channel bindings need the information held in browser cookies. Therefore front-channel SLO will work with SP4 (Backdoor) if initiated by some other SP's, but SP4 can only initiate back-channel SLO (which is not supported by many of the SP's above.)
