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. It is best utilized when an option of cifsacl is specified when mounting a cifs share in conjunction with winbind facility of Samba suite. Whether a security descriptor to be set is applied or not is determined by the CIFS/SMB server. OPTIONS

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
