Delete and Rename Inhibit flags causes access denied to folders via AFP

Delete and Rename Inhibit flags causing access denied to folders via AFP
Access denied AFP
Home directories locked AFP

There are two known work-arounds for this issue:

1. Copy the contents of the locked directory out to a temporary directory.  Delete and re-create the directory and re-assign the appropriate rights.  Once this is complete, copy back in the data from the temporary directory.  (It would also be possible to remove the hidden files ((all prefixed with a .)))

2. Remove the delete and rename inhibit flags from the 'locked' directories

The issue is caused by the delete and rename inhibit flags on the directories.
