+Configuring NFS4 ACLs in Samba3
+===============================
+Created: Peter Somogyi, 2006-JUN-06
+Last modified: Peter Somogyi, 2006-JUL-20
+Revision no.: 4
+-------------------------------
+
+
+Parameters in smb.conf:
+=======================
+
+Each parameter must have a prefix "nfs4:".
+Each one affects the behaviour only when _setting_ an acl on a file/dir:
+
+mode = [simple|special]
+- simple: don't use OWNER@ and GROUP@ special IDs in ACEs. - default
+- special: use OWNER@ and GROUP@ special IDs in ACEs instead of simple user&group ids.
+Note: EVERYONE@ is always processed (if found such an ACE).
+Note2: special mode will have side effect when _only_ chown is performed. Later this may be worked out.
+
+Use "simple" mode when the share is used mainly by windows users and unix side is not significant. You will loose unix bits in this case.
+It's strongly advised setting "store dos attributes = yes" in smb.conf.
+
+chown = [true|false]
+- true => enable changing owner and group - default.
+- false => disable support for changing owner or group
+
+acedup = [dontcare|reject|ignore|merge]
+- dontcare: copy ACEs as they come, don't care with "duplicate" records. Default.
+- reject: stop operation, exit acl setter operation with an error
+- ignore: don't include the second matching ACE
+- merge: OR 2 ace.flag fields and 2 ace.mask fields of the 2 duplicate ACEs into 1 ACE
+
+Two ACEs are considered here "duplicate" when their type and id fields are matching.
+
+Example:
+
+[smbtest]
+path = /tests/psomogyi/smbtest
+writable = yes
+vfs objects = aixacl2
+nfs4: mode = special
+nfs4: chown = yes
+nfs4: acedup = merge
+
+Configuring AIX ACL support
+==============================
+
+Binaries: (default install path is [samba]/lib/vfs/)
+- aixacl.so: provides AIXC ACL support only, can be compiled and works on all AIX platforms
+- aixacl2.so: provides AIXC and JFS2-NFS4 ACL support, can be compiled and works only under AIX 5.3 and newer.
+NFS4 acl currently has support only under JFS2 (ext. attr. format must be set to v2).
+aixacl2.so always detects support for NFS4 acls and redirects to POSIX ACL handling automatically when NFS4 is not supported for a path.
+
+Adding "vfs objects = aixacl2" to a share should be done only in case when NFS4 is really supported by the filesystem.
+(Otherwise you may get performance loss.)
+
+For configuration see also the example above.
+
+General notes
+=============
+
+NFS4 handling logic is separated from AIX/jfs2 ACL parsing.
+
+Samba and its VFS modules dosn't reorder ACEs. Windows clients do that (and the smbcacl tool). MSDN also says deny ACEs must come first.
+NFS4 ACL's validity is checked by the system API, not by Samba.
+NFS4 ACL rights are enforced by the OS or filesystem, not by Samba.
+
+The flag INHERITED_ACE is never set (not required, as doesn't do WinNT/98/me, only since Win2k).
+Win2k GUI behaves strangely when detecting inheritance (sometimes it doesn't detect,
+but after adding an ace it shows that - it's some GUI error).
+
+Unknown (unmappable) SIDs are not accepted.
+
+TODOs
+=====
+- Creator Owner & Group SID handling (same way as posix)
+- the 4 generic rights bits support (GENERIC_RIGHT_READ_ACCESS, WRITE, EXEC, ALL)
+- chown & no ACL, but we have ONWER@ and GROUP@
+- DIALUP, ANONYMOUS, ... builtin SIDs
+- audit & alarm support - in theory it's forwarded so it should work, but currently there's no platform which supports them to test
+- support for a real NFS4 client (we don't have an accepted API yet)
