auth.sh needs to contain a valid user for the client machine (usually with administrative privileges), as compared to the rsyncd user auths.  It is then used to remotely kick off scripts on the client side (as the user specified in auth.sh).

I will try the full path now. However, I did su - backuppc account on
backup server and noted 'at' was in the path. I will give the full
path a try now.

Actually, auth.sh and rsyncd.conf/rsync.secrets was configured
correctly. I went over that again and again. User mentioned in
rsyncd.conf was configured in rsync.secrets in user:pw format.  I must
mention, the windows client installer,  though it asked for
username/password, installer didn't put anything in rsync.secrets and
rsyncd.conf which I realized some time after installation(but before
posting here) and winxp was rebooted after those files were modified.

What made the dump working for me was below two additional settings,
$Conf{RsyncdPasswd} = 'Ba....';
$Conf{RsyncdUserName} = 'backuppc';

backuppc is the user I have in rsynced.conf/rsync.secrets/auth.sh and
in windowsxp's backup configuration file (.pl) where the above two
parameters are configured.

I didn't see any mention of this step on the blog. I hope the two
parameters configured above are part of the process. If not then
something isn't working the way it should.
