some miscommunication probably because of my sketchy explanation.

My image is
term% cat /mnt/factotum/ctl
key proto=p9sk1 dom=aichi-u.ac.jp user=arisawa !password?
key proto=p9sk1 dom=aichi-u.ac.jp user=bootes !password?
disabled key proto=p9sk1 dom=inside.plan9.bell-labs.com user=arisawa
!password?
key proto=p9sk1 dom=grid.bell-labs.com user=arisawa !password?
term%

Factotum knows attribute value list is useless or not.
If the list is confirmed useless in authentication process,
I would like disabled is put at the beginning.
Next time I will fix the problem and put
key proto=p9sk1 dom=outside.plan9.bell-labs.com user=arisawa !password?
then I will get
term% cat /mnt/factotum/ctl
key proto=p9sk1 dom=aichi-u.ac.jp user=arisawa !password?
key proto=p9sk1 dom=aichi-u.ac.jp user=bootes !password?
key proto=p9sk1 dom=outside.plan9.bell-labs.com user=arisawa !password?
key proto=p9sk1 dom=grid.bell-labs.com user=arisawa !password?
term%

If I put wrong user name, say alice instead of arisawa, then factotum
is not
authenticated. therefore we will get:
term% cat /mnt/factotum/ctl
key proto=p9sk1 dom=aichi-u.ac.jp user=arisawa !password?
key proto=p9sk1 dom=aichi-u.ac.jp user=bootes !password?
key proto=p9sk1 dom=outside.plan9.bell-labs.com user=arisawa !password?
key proto=p9sk1 dom=grid.bell-labs.com user=arisawa !password?
disabled key proto=p9sk1 dom=outside.plan9.bell-labs.com user=alice
!password?

Wrong user name does no harm

The current problem is in that factotum put every data even if the data
is confirmed
invalid.

The above is rough sketch. we should examine more.
