Let's step back a second and revisit the key pair that you'd generated. From your post:

Quote:
I used 'ssh-keygen -b 1024 -P "" -t dsa' to generate the Public-Key
Passphrase has apparently gained the misnomer of equal to the password, unfortunately. It's not, and it's intended to serve as a means to ensure public sharing of the key-pair without granting full account access to the remote host. Also, you don't need (or want) to specify your passphrase (ie, -P "") on the command-line, as it can be used against you, should anyone gain access to your key-pair and/or .sh_history file.

Instead of using -P (which is really intended to allow for revision of the passphrase in a given key-pair), let the ssh-keygen program prompt you for your passphrase. Leave all other switches as they are, but scratch the
Code:
-P ""

options. The program will prompt you for the empty passphrase..to which you'll just enter twice. It doesn't matter what key type you're creating either..same goes for rsa and dsa.

Lastly, just be sure that you're placing the Public Key into the remote user's .ssh directory as well. You don't have to have identical users between the machines..or even have separate machines for that matter (ie, unilover@localhost can access unilever@localhost, much the same as unilover@localhost can access unilever@remotehost or unilover@remotehost). So long as the key placement is done right..you can automate the login with an empty passphrase.
