[Bug 724571] [NEW] Some shared folders (root folders and non root folders) are seen as files on Windows XP and Windows 2003 having ACL enabled

[Leonardo Borda]

Public bug reported:

Binary package hint: samba

Hi Guys,

Some samba shared folders (root folders and non root folders) are seen as files
on Windows XP and Windows 2003 when ACL is enabled.
If I rename a folder, delete it or create a new folder, a different folder
becomes a file. 

We have identified that this error occurs when a "file" has acl mask set to
mask::---  in the directory. ie:
# file: file.exe
# owner: Domain+user
# group: BUILTIN+administrators
user::rw-
group::r-x      #effective:---
group:Domain+domain\040admins:rwx       #effective:---
group:Domain+admindd:rwx        #effective:---
group:Domain+adminddc:rwx       #effective:---
mask::---
other::---

Here is the smb.conf shared section..

[shared]
  comment = Shared Area
  path = /samba/shared
  read only = No
  create mask = 0770
  force security mode = 0700
  inherit acls = Yes
  hide unreadable = Yes
  fstype = XFS 1.2
  vfs objects = full_audit, shadow_copy

Steps to reproduce.

1. Enable acls
2. Configure samba as described above.
3. create 3 folders, create a file inside each folder and set one of the files
as follow:
sudo setfacl -m m:--- filename
4. Join a winxp or windows 2003 into a domain and try to access a shared
folder.
