Well, to be safe you'd want to do

scp id_dsa.pub testbar:id_dsa.foo
ssh testbar
[enter password]
cat ~/id_dsa.foo >> ~/.ssh/authorized_keys

The command you included above would clobber any keys that
are already in ~/.ssh/authorized_keys.

(Note also that 'david at testbar:/home/david/.ssh' is rather
long; the short form is 'david at testbar:.ssh'. And since ssh
defaults to using the same username on your remote machine
as on your local one, you can shorten it further to
'testbar:.ssh'.)

However, that probably doesn't explain your current problem.

Try doing

ssh -v fast

and send us the results from that. The verbose logging in
ssh is quite handy.
