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:CIFSTESTDOMuser2:DENIED/0x1/D"      <file_name>      setcifsacl      -a
          "ACL:CIFSTESTDOMuser1: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:CIFSTESTDOMuser1:ALLOWED/0x1f/CHANGE" <file_name>

   Set an ACL
          setcifsacl      -S       "ACL:CIFSTESTDOMAdministrator:0x0/0x0/FULL,ACL:CIFSTESTDOMuser2:0x0/0x0/FULL"
          <file_name>

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