NAME
       setcifsacl - Userspace helper to alter an ACL in a security descriptor
       for Common Internet File System (CIFS)

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. /etc/cifs-utils/idmap-plugin should be a symlink that
       points to the correct plugin to use.

OPTIONS
       -h
	   Print usage message and exit.
       -v
	   Print version number 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

EXAMPLES
       Add an ACE
       setcifsacl -a "ACL:CIFSTESTDOM\user2:DENIED/0x1/D" <file_name>
       setcifsacl -a "ACL:CIFSTESTDOM\user1:ALLOWED/OI|CI|NI/D" <file_name>

       Delete an ACE
       setcifsacl -D "ACL:S-1-1-0:0x1/OI/0x1201ff" <file_name>

       Modify an ACE
       setcifsacl -M "ACL:CIFSTESTDOM\user1:ALLOWED/0x1f/CHANGE" <file_name>

       Set an ACL
       setcifsacl -S "ACL:CIFSTESTDOM\Administrator:0x0/0x0/FULL,
       ACL:CIFSTESTDOM\user2:0x0/0x0/FULL" <file_name>

NOTES
       Kernel support for getcifsacl/setcifsacl utilities was initially
       introduced in the 2.6.37 kernel.
