Mmh - I have a Mac and use a native login, where you specify the login name already in the ssh command. I could imagine (when I look at some screenshost from putty), that it's putty who is asking for the "login:" name, not the machine you login to.
So you could use Banner /etc/foobar.txt in /etc/ssh/sshd_config (needs restart) to point to a file which should be listed.
There is also pam_echo, but this I didn't get working.
