1 This patch has been taken against SAMBA_3_0 Release 20028.
3 The patch basically moves the GPFS-ACL functionalities into the new GPFS VFS module( vfs_gpfs ).
5 Please read SAMBA_3_0/source/modules/README.nfs4acls.txt - generalised README file on Samba support for NFS4-ACLS.
6 This README file is specific for GPFS only.
8 Configuring GPFS ACL support
9 ===============================
11 Binary: (default install path is [samba]/lib/vfs/)
14 Its compiled by default, no additional configure option needed.
16 To enable/use/load this module, include "vfs objects = gpfs" in the smb.conf file under concerned share-name.
27 Adding "vfs objects = gpfs" to a share should be done only in case when NFS4 is really supported by the filesystem.
28 (Otherwise you may get performance loss.)
30 ==================================================
31 Below are some limitations listed for this module:
32 ==================================================
33 1. When a child file or child directory is created, the results are a bit different from windows as specified below:
35 Eg: Prent directory is set to have 2 ACES - full access for owner and everyone
37 Default ACL for Windows: 2 aces: allow ACE for owner and everyone
38 Default ACL for GPFS: 6 aces: allow and deny ACEs for owner, group and everyone
40 The below mentioned inheritance flags and its combinations are applied only to the owner ACE and not to everyone ACE
42 "fi"------>File Inherit
43 "di"------>Directory Inherit
44 "oi"------>Inherit Only
47 Parent dir: no inheritance flag set
48 Windows: index=0: GPFS(special mode): index=0: GPFS(simple mode): index=0:
