Forward port of #5190 to stable12

Signed-off-by: Arthur Schiwon <blizzz@arthur-schiwon.de>

remove unnecessary lines…

Signed-off-by: Arthur Schiwon <blizzz@arthur-schiwon.de>

Otherwise it might be that authentication apps are being disabled on
during operation while in fact the session handler has hiccup.
