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.
