@ERROR: auth failed on module test

[MICHAEL R. LEFEBVRE]

rsync: connection unexpectedly closed (88 bytes read so far)
rsync error: error in rsync protocol data stream (code 12) at
io.c(139)

I'm getting the above error when trying to use rsync over port 873. 
The command I'm using is :
rsync -avz root at sundog::test ./
 the /etc/rsyncd.conf contains the following

auth users = root
uid = root
gid = staff
 
[test]
path = /export/home/mrl315

Any suggestions would be appreciated - I've been trying to get this
working off and on for about 2 weeks now.

Regards,
