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.
