I don't see anything obvious that would be wrong - have you
checked /var/log/auth.log (or similar) for any
warnings/errors from Dropbear? I assume that logging in as
the user with a password works fine? The only other common
issue is possibly line wrapping/formatting in the
authorized_keys file if it was copied/pasted. The homedir
for the user is set correctly in /etc/passwd?
