SSH - RSA still prompting for password?

[oguruma]

I am trying to set up backups for a remote webserver via rsync.

I have made RSA keys via ssh-keygen (on my NAS) and pasted the public key into the authorized_keys file (of the webserver).

I verified that there is a key in id_rsa (on the NAS).

When I SSH from the NAS into the web server I am still prompted for a password.

I have only ever done this in PuTTY, in which you navigate to the location of the private key, so I am sure I am doing something wrong.

Why am I still prompted for a password when I try to SSH into my webserver? Do I have to move the key from id_rsa to somewhere else? Do I have to make an argument when I use the ssh command on the NAS?

Anything recorded to /var/log/auth.log ?
