This is the answer.
You rely on your shell being smart enough to pick environment variable as
operational directive, but SSH knows nothing about it and fails.

Which explains the failure.

Configure Cygwin's NSS to your heart's content.

Speaking of which, if you move $HOME outside Cygwin root, I would strongly
suggest spending some time in fstab, setting up cygdrive to noacl mode.
F.e.
none /cygdrive cygdrive noacl,binary,nouser,posix=0 0 0
