SYNOPSIS
********
setcifsacl [-v|-a|-D|-M|-S] "{one or more ACEs}" {file system object}
***********
DESCRIPTION
***********
This tool is part of the cifs-utils suite.
\ **setcifsacl**\ is a userspace helper program for the Linux CIFS client
file system. It is intended to alter an ACL of a security descriptor
for a file system object. Whether a security descriptor to be set is
applied or not is determined by the CIFS/SMB server.
This program uses a plugin to handle the mapping of user and group
names to SIDs. ``@pluginpath@`` should be a symlink that points to the
correct plugin to use.

OPTIONS
*******
\ **-h**\
Print usage message and exit.

\ **-a**\
Add one or more ACEs to an ACL of a security descriptor. An ACE is
added even if the same ACE exists in the ACL.
\ **-D**\
Delete one or more ACEs from an ACL of a security descriptor. Entire
ACE has to match in an existing ACL for the listed ACEs to be deleted.
\ **-M**\
Modify one or more ACEs from an ACL of a security descriptor. SID and
type are used to match for existing ACEs to be modified with the list
of ACEs specified.
\ **-S**\
Set an ACL of security descriptor with the list of ACEs Existing ACL
is replaced entirely with the specified ACEs.
Every ACE entry starts with "ACL:" One or more ACEs are specified
within double quotes. Multiple ACEs are separated by a comma.
Following fields of an ACE can be modified with possible values:
\ **SID**\ - Either a name or a raw SID value.
\ **type**\ - ALLOWED (0x0), DENIED (0x1), OBJECT_ALLOWED (0x5), OBJECT_DENIED (0x6)
\ **flags**\ - OBJECT_INHERIT_FLAG (OI or 0x1), CONTAINER_INHERIT_FLAG (CI or 0x2), NO_PROPAGATE_INHERIT_FLAG (NI or
0x4), INHERIT_ONLY_FLAG (IO or 0x8), INHERITED_ACE_FLAG (IA or 0x10)
or a combination/OR of these values.
\ **mask**\ - Either one of FULL, CHANGE, READ, a combination of R W X D P O, or a hex value
