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>
