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 introduced in the 2.6.37
