[9fans] factotum/ssh issue

[Sam <sah@softcardsystems.com>]

Hola,

We finally stopped working long enough to upgrade
to 4e last week and I have to admit, the first
time I was auto-login'd to a remote unix box
after having stored the key in factotum I was
exuberant.

I have a minor nitpick, though.  When I ssh'd into a unix
box for the first time I was prompted to add the key
(not real security, but good enough for me), then I was
asked for the password to the machine.  My trigger happy finger
decided to hit enter, thereby entering a nil password
and failing to authenticate.  Further attempts to
ssh into the machine failed because factotum stored the
incorrect password.  I needed to become accustomed to
key management with factotum anyway, but it still seems improper
to store the password if password authentication fails.

I looked at removing the server key if ssh password authentication
fails, but there doesn't seem to be an rpc mechanism in factotum
to do this.

Cheers,

Sam
