@ERROR: access denied

[ben-incomum at pendrell.textdrive.com]

I'm trying to set up an rsync daemon on my OS X machine to sync my
remote subversion repositories. My config file /etc/rsyncd.conf looks
like this:

motd file = /etc/motd
max connections = 25
syslog facility = local3

[repositories]
  comment = Subversion Repositories
  path = /usr/local/repositories
  read only = no
  list = yes
  hosts allow = 127.0.0.1
  auth users = username
  secrets file = /etc/rsyncd.secrets

However running "rsync username at localhost::repositories" I get:

@ERROR: access denied to repositories from localhost (::1)
rsync: connection unexpectedly closed (71 bytes read so far)
rsync error: error in rsync protocol data stream (code 12) at io.c(189)

What am I missing here?

Thanks,
Ben
