openssh unix dev - Nov 2000 - OpenSSH_2.3.0p1: Change request regarding "authorized_keys"

Hello,

in OpenSSH_2.3.0p1 multiple keys can be added to .ssh/authorized_keys, 
and they actually work. However it would be desirable to know _which_ 
key led to authorization. Currently the syslog only says:

sshd[...]: Accepted rsa for ROOT from 192.168.0.15 port 964

Should/could the fingerprint of the key or at least the index of the 
key (line number) in authorized_keys be shown? Or is it a security risk 
to display such information?

Regards,
Ulrich
