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>

       Kernel support for getcifsacl/setcifsacl utilities was initially intro-
