F-Secure client talking to OpenSSH server

[dobbie]

Hello,

I need to let one server running Solaris 5.6 and F-Secure SSH 3.0.1 
transfer files to another server running OpenSSH 4.3p1 using sftp.
I have put the public key from the client into the server's $HOME/.ssh 
directory, but OpenSSH does not recognize it:
debug: server offers auth methods 
'publickey,password,keyboard-interactive'.
debug: Ssh2AuthClient/sshauthc.c:316/ssh_authc_completion_proc: Method 
'publickey' disabled.
debug: server offers auth methods 
'publickey,password,keyboard-interactive'.
debug: Ssh2AuthPasswdClient/authc-passwd.c:113/ssh_client_auth_passwd: 
In Batchmode, so we're not asking the user for password.
debug: Ssh2AuthClient/sshauthc.c:316/ssh_authc_completion_proc: Method 
'password' disabled.
debug: server offers auth methods 
'publickey,password,keyboard-interactive'.
debug: Ssh2Common/sshcommon.c:137/ssh_common_disconnect: DISCONNECT 
received: No further authentication methods available.

Any hints ?
