Perhaps the issue is with the steps you took to generate the key.  The
message you show above does not show that ssh is prompting you for
your login password, it shows that it's prompting you for your key
password.

Note that you can generate your dsa keys either with or without a
password.  I always generate mine without a password, so I don't know
what I would see with the password.  But I do know that when I don't
have a key set up at all, I get a different password prompt than the
one you show.

Here's from the ssh-keygen man page:

   Normally this program generates the key and asks for a file in which
   to store the private key.  The public key is stored in a file with the
   same name but ``.pub'' appended.  The program also asks for a
   passphrase.  The passphrase may be empty to indicate no passphrase
   (host keys must have an empty passphrase), or it may be a string of
   arbitrary length.  A passphrase is similar to a password, except it
   can be a phrase

I hope this helps.
