Good day!
Request:
More informational error/warning/info text displayed to user instead of
being dropped at the password prompt.
Notes from testing:
Affected openssh version - All tested (ex. 7.2p2, OpenSSH_5.3p1)
Affected OS - All tested (OpenSUSE Leap 42.2, Arch Linux, SLES 11 SP4,
HP/UX)
Hence, submitting this upstream.
Concern:
When a private key (ex. key1) is used and there's a public key with the
same file name+pub extension (ex. key1.pub) in the same directory, the
automatic login will fail and will drop the user to the password prompt.
Sample openssh version:
santi@osuse:~> rpm -qi openssh

Summary : Secure Shell Client and Server (Remote Login Program)
Description :
SSH (Secure Shell) is a program for logging into and executing commands
on a remote machine. It is intended to replace rsh (rlogin and rsh) and
provides openssl (secure encrypted communication) between two untrusted
hosts over an insecure network.
xorg-x11 (X Window System) connections and arbitrary TCP/IP ports can
also be forwarded over the secure channel.
Distribution: openSUSE Leap 42.2
santi@osuse:~>
Observation:
Output will display the key as type 1 (debug1) and an address in debug2.
debug1: identity file key1 type 1
..
debug2: key: key1 (0x55c14718c180), explicit
