It would be helpful if you could give more details and say what
command you are trying and its output with the verbose flag set like
this -vvv.
Yep, the -vvv option on the remote ssh and taking a look at /var/log/messages
and /var/log/secure should provide details about why failure happens.
Perhaps the sshd_config file is set to only allow public key connections?
That would certainly make a password attempt fail (and is how I have my
server setup for remote connections versus local network connections
where I do allow passwords).
