I beleive you must have a factotum running, its started at boot,
so I would expect it to prompt you for a key (user & password in this case).

If this happened once and you have the wrong key
then factotum will rembember them until reboot or its
told to forget.

rob (pike) posted a neat script, delkey, a while back
to simplify the deletion of unwanted/bad keys. I don't
know why this didn't make it into the distribution.

I run a simgle plan9 machine so I have no secstore. In my
$user/lib/profile I have:

	echo  -n 'factotum '
	auth/aescbc -d < $home/lib/wallet | read -m > /mnt/factotum/ctl

This works similarly though less securely (somone could steal
my wallet and spend weeks cracking it).
