Problems with ssh-keygen

Hi all,

as some of you suggested I used ssh-keygen to automate my sftp connection but the server side still asking me for a password even if a transfered my public key to it.

I will give you the steps I did for the ssh-keygen installation.

1. ssh-keygen -t dsa (on the openssh client side)
2. put the .ssh/id_dsa.pub into .ssh/authorized_keys (on the openssh server side)
3. try to connect with sftp (still asking for a password.

Someone suggested me that the server side and client side had to have the same username/password. Is it a reality?

Also, is there a possible miscommunication between two server that are not the same, one HP and one Sun?

Thanks in advance for your answers.
