rsync and ssh keys help

view story

http://www.unix.com – Not specifically a mac question, but it's what I am using. I am setting up some replication for some file shares using rsync. The problem is that I am being given a little bit of a twist - I'm supposed to use a non-admin account to do it with. I have 2 boxes - Master and Slave with 1 account (sharesync). I setup a pub/private key pair and am able to successfully ssh from slave to master. I can also run rsync from the slave to the master. My problem is that rsync fails, complaining that it can't change ownership/permissions on the files that it just placed on the slave. This makes sense (HowTos)
