  After upgrading a 2.1 machine to the netbsd-3 branch, ssh started
to sprout strange behaviour at its password prompt:

|       % ssh asparagus
|       Password:         <--- does not even wait for input here
|       Response:
|       mjl@asparagus's password:

  This is somehow related to PAM, since setting "UsePAM no" in sshd.config
restores the previous normal behaviour.

  I first thought this might be related to old S/Key data lying around
but Hauke Fath mentions:

| FWIW, I see this on a (pretty vanilla) sparc installation. S/Key has
| never been used on the machine.

  I set priority high because this will seriously confuse people who
upgrade to 3.0.

  ssh into an upgraded machine?
