restricting rsync over ssh

[Brian D. Hamm]

Is it true that when running rsync via ssh (i.e. rsync -e ssh ...) the
rsyncd.conf file is not applicable on the remote since rsync is launched
via the ssh exec call once connected rather than from rsyncd as in a
direct connect.

If so, I am trying to find the best way to restrict rsync -e ssh on the
remote machine.  Prepending the authorized_keys entry with
command='rsync ...' 1024... results in the 'Protocol mismatch - is your
shell clean?' error.

Thanks,
