[Samba] file delete problem

[Ryan Suarez]

Using samba v3.3.5 with winbind.  'force user' parameter is set on share.

- upload files to share work fine
- create subfolders on share work fine
- delete subfolders on share work fine

Problem is when trying to delete files.  Get the error (on vista client) 
"Destination Folder Access Denied:You need permission to perform this 
action"

I can delete the file fine as the user directly from the samba server.

If I chmod 757 the share then the deletes work.

I don't really want to leave the perms 757.  How can I get deletes to 
work with permission 755?

thanks,
Ryan
