10 setcifsacl [-v|-a|-D|-M|-S] "{one or more ACEs}" {file system
11 object}
12
14 This tool is part of the cifs-utils suite.
15
16 setcifsacl is a userspace helper program for the Linux CIFS client file
17 system. It is intended to alter an ACL of a security descriptor for a
18 file system object. Whether a security descriptor to be set is applied
19 or not is determined by the CIFS/SMB server.
20
21 This program uses a plugin to handle the mapping of user and group
22 names to SIDs. /etc/cifs-utils/idmap-plugin should be a symlink that
23 points to the correct plugin to use.
24
26 -h Print usage message and exit.
27
28 -v Print version number and exit.
29
30 -a Add one or more ACEs to an ACL of a security descriptor. An ACE
31 is added even if the same ACE exists in the ACL.
32
33 -D Delete one or more ACEs from an ACL of a security descriptor.
34 Entire ACE has to match in an existing ACL for the listed ACEs
35 to be deleted.
36
37 -M Modify one or more ACEs from an ACL of a security descriptor.
38 SID and type are used to match for existing ACEs to be modified
39 with the list of ACEs specified.
40
41 -S Set an ACL of security descriptor with the list of ACEs Existing
42 ACL is replaced entirely with the specified ACEs.
43
44 Every ACE entry starts with "ACL:" One or more ACEs are speci‐
45 fied within double quotes. Multiple ACEs are separated by a
46 comma.
47
48 Following fields of an ACE can be modified with possible values:
49
50 · SID - Either a name or a raw SID value.
51
52 · type - ALLOWED (0x0), DENIED (0x1), OBJECT_ALLOWED (0x5),
53 OBJECT_DENIED (0x6)
54
55 · flags - OBJECT_INHERIT_FLAG (OI or 0x1), CON‐
56 TAINER_INHERIT_FLAG (CI or 0x2), NO_PROPAGATE_INHERIT_FLAG (NI
57 or 0x4), INHERIT_ONLY_FLAG (IO or 0x8), INHERITED_ACE_FLAG (IA
58 or 0x10) or a combination/OR of these values.
59
60 · mask - Either one of FULL, CHANGE, READ, a combination of R W
61 X D P O, or a hex value.
62
64 Add an ACE
65 setcifsacl -a "ACL:CIFSTESTDOMuser2:DENIED/0x1/D" <file_name> set‐
66 cifsacl -a "ACL:CIFSTESTDOMuser1:ALLOWED/OI|CI|NI/D" <file_name>
67
68 Delete an ACE
69 setcifsacl -D "ACL:S-1-1-0:0x1/OI/0x1201ff" <file_name>
70
71 Modify an ACE
72 setcifsacl -M "ACL:CIFSTESTDOMuser1:ALLOWED/0x1f/CHANGE" <file_name>
73
74 Set an ACL
75 setcifsacl -S "ACL:CIFSTESTDOMAdministrator:0x0/0x0/FULL,ACL:CIF‐
76 STESTDOMuser2:0x0/0x0/FULL" <file_name>
