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.
