However it also means that when the user is simultaneously logged in twice, he will not be able to access the encrypted volume in the second session either. It also means that the process that mounts the volume must run in the namespace of the user's session (setuid helper would be needed instead of using system service to mount the volume). -- Tomas Mraz No matter how far down the wrong road you've gone, turn back.
