The SRC is via a default network share: //$
The DST is a local directory.
So there is only onw instance of rsync running (no "sending" end).

The Owners/Groups on the SRC side are:
Group: COMPUTER\Administrators
User:  DOMAIN\SpecificUser

The Owners/Groups on the DST side end up as:
User:  DOMAIN\Administrator
Group: DOMAIN\Domain Users
Group: Everyone

Prior to using an ACL enabled rsync (and rsync without -A) they were:
User:  DOMAIN\Administrator
Group: DOMAIN\Domain Users
Group: Everyone

I have read (many times) and
/etc/passwd and /etc/group look OK, they seem to have all the SIDs in them, 
including one for SpecificUser.

I also just tried "rsync -avPA --super ..." with no luck.

Could the problem be related to rsync only running on a single machine with 
no "remote" side?
