SSH Prompts for Password After Keys Setup Successfully
I setup the keys between 2 servers, but my user account has no password specified for it (never set one up on the account for security reasons). When I try to SSH to the server, SSH prompts for a password that doesn't exist (so I can never connect successfully).
Note: 'passwd -d Rynok' removes the password & disables the account (this allows SSH to work correctly, but unfortunately this is also a security risk)
Summary (for you quick readers):
SSH Keys Setup so that Rynok@ServerA->Rynok@ServerB
No password is set on 'Rynok' user.
SSH Prompts for a Password.
I set a password on 'Rynok@ServerB'
SSH Works w/o a Prompt!
Any idea why it only prompts me because there is no password set?
Is this normal/expected behavior?
Can I change a config so this doesn't happen?

Recently I have been playing with password ageing and the usage of ssh keys. I have found that if usePAM yes (default) is set in the /etc/ssh/sshd_config file then any password ageing and inactiivity can adversely affect a client with ssh keys.

ssh-keysign
SSH-KEYSIGN(8) BSD System Manager's Manual SSH-KEYSIGN(8)
NAME
ssh-keysign -- ssh helper program for hostbased authentication
SYNOPSIS
ssh-keysign
DESCRIPTION
ssh-keysign is used by ssh(1) to access the local host keys and generate the digital signature required during hostbased authentication with
SSH protocol version 2.
ssh-keysign is disabled by default and can only be enabled in the the global client configuration file /etc/ssh/ssh_config by setting
HostbasedAuthentication to ``yes''.
ssh-keysign is not intended to be invoked by the user, but from ssh(1). See ssh(1) and sshd(8) for more information about hostbased authen-
tication.
FILES
/etc/ssh/ssh_config
Controls whether ssh-keysign is enabled.
/etc/ssh/ssh_host_dsa_key, /etc/ssh/ssh_host_rsa_key
These files contain the private parts of the host keys used to generate the digital signature. They should be owned by root, read-
able only by root, and not accessible to others. Since they are readable only by root, ssh-keysign must be set-uid root if hostbased
authentication is used.

ssh-keysign first appeared in OpenBSD 3.2.
