Well, it should have been "yes" given my understanding of what you
were trying to do.  However, I think now that understanding was
faulty.

You probably should make new keys on lemna, rather than copying them
over from salmo.  On lemna, run:

  ssh-keygen -t dsa 

If dsa keys are what you want.  You should _add_ (as in "append") the
resulting .ssh/id_dsa.pub to the appropriate users
.ssh/authorized_keys on salmo.  Likewise, you should _add_ salmo's
.ssh/id_dsa.pub to lemna's .ssh/authorized_keys.

Permissions and ownership are also important.  The .ssh directory
should be 0700, and .ssh/id_dsa should be 0600.  I seem to recall
something about write permission on the home directory being important
too, but I couldn't find the specifics.  Something about a group
member or another user should not being able to modify the .ssh
permissions.
