The difference is probably just a missing entry for "0" in /etc/group.

If that's not the cause, try kicking ssh into debug mode ("ssh -vvv 
whatever") and see what it says.

/dev/tty is a special case that allows a process to access its 
controlling terminal.

Not for passwords/passphrases.  Consider where ssh's stdin is coming 
from in this example:

grep foo bar | ssh someserver baz

plus ssh need /dev/tty to access it's controlling terminal so it can 
turn echo off while reading passwords.

     Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
