There where several patches on the list to log the key comment,
but they where not included in openssh.

Without patching, you can run the sshd with LogLevel=VERBOSE.
This will log the fingerprint of the key used for authentication.
(With "ssh-keygen -l -f authorized_keys" you get all fingerprints
of the public keys in the file)
