[Samba] cannot delete or rename after upgrade to 3.5.4

[Gary Casterline]

After upgrading samba from 3.4.8 to 3.5.4, we find that for some of our
shares, we cannot delete or rename files or folders.

Windows mappings to the [home] share can create new folders and files
but when we try to delete or rename we get an error messages like:
	
	You need permission to perform this action

	You require permission from
	S-1-5-21-xxxxxxx-yyyyyyyyyy-zzzzzzzzzz-www
	to make changes to this file

The same actions work fine for other shares like [cs] below.

Here are parts of our smb.conf:
