I'm not sure which way you are trying to connect, but here is what I did
to access my Debian machine from a Windows machine with WinSCP:

In Debian box in file /etc/ssh/sshd_config I have
AuthorizedKeysFile %h/.ssh/authorized_keys
PubkeyAuthentication yes

Don't forget to restart sshd, if you need to change something in the

In my home dir in Debian box I have
.ssh/authorized_keys in which I put the public key of the RSA key pair
~$ cat id_rsa.pub >> .ssh/authorized_keys

In Windows machice I start WinSCP and browse for the secret key of the
RSA key pair (id_rsa.ppk), which I have converted into ppk format
(id_rsa -> id_rsa.ppk) with puttygen.exe.

I'm not sure if cuteFTP can handle the RSA key in the openssh format.

In my configuration the sshd uses the syslog facility and you can get
more verbose output into the /var/log/syslog, if you set the LogLevel to
VERBOSE or DEBUG or even DEBUG3 in the /etc/ssh/sshd_config (see man
sshd_config for more details). Don't forget to restart sshd.
