So I have multiple keyslots in use:
* 1 for admin
* 1 for userA
* 1 for userB

userA leaves without divulging passphrase; userB is out of reach.

How do I know which slot to luksKillSlot?

Have I missed something?

A solution may be an optional name that shows up in luksDump and is setup at
creation time:
  cryptsetup luksAddKey --name "admin" /dev/sda1
  cryptsetup luksAddKey --name "johndoe" /dev/sda1


cheers

David

Specify the slot number when adding keys and keep a list of 'slot
number = user' entries somewhere.

After the fact ... kill both users and re-add the one that should remain.

Cheers,

OK, glad I didn't miss anything.

I guess "somewhere" could/should be the header :)

So clearly there's a usability problem there.
