It doesn't work that way in AFS - AFS does have some implicit rights,  
but if you don't have a read ACL for a directory, you can't access  
files in it, regardless of their ownership.

Files that get written to a volume in a cell are owned by the user's  
ID in that cell's protection service database, not by the local UID  
on the machine which wrote them.
