Hi
How can I find out which key slot was used to decrypt
mounted partition?
It's the following use case:
* I have three users on a notebook.
* Each has his own password for LUKS:
* User1: Key-Slot 1
* User2: Key-Slot 2
* User3: Key-Slot 2
* Now I want a script to find out, which user decrypted
the drive (and is therfore sitting in front of the
laptop).
* With this knowledge, I want to autologon the user that
decrypted the hardisk to the desktop.
This way, the user only needs to give his password (the
luks-password) once and does not have to choose his username
and password on KDM/GDM login screen.
Any idea? I didn't find anything, neither in the manpage,
nor with cryptsetup status, nor in /proc nor /sys, nor with
Google.
Thank you
Regards
Marc
