.SH "NAME"
smbcacls \- Set or get ACLs on an NT file or directory names
.SH "SYNOPSIS"
.HP \w'\ 'u
smbcacls {//server/share} {/filename} [\-D|\-\-delete\ acl] [\-M|\-\-modify\ acl] [\-a|\-\-add\ acl] [\-S|\-\-set\ acl] [\-C|\-\-chown\ name] [\-G|\-\-chgrp\ name] [\-I\ allow|remove|copy] [\-\-numeric] [\-t] [\-U\ username] [\-d] [\-e] [\-m|\-\-max\-protocol\ LEVEL] [\-\-query\-security\-info\ FLAGS] [\-\-set\-security\-info\ FLAGS] [\-\-sddl] [\-\-domain\-sid\ SID]
.SH "DESCRIPTION"
.PP
This tool is part of the
\fBsamba\fR(7)
suite\&.
.PP
The
smbcacls
program manipulates NT Access Control Lists (ACLs) on SMB file shares\&. An ACL is comprised zero or more Access Control Entries (ACEs), which define access restrictions for a specific user or group\&.
.SH "OPTIONS"
.PP
The following options are available to the
smbcacls
program\&. The format of ACLs is described in the section ACL FORMAT
.PP
\-a|\-\-add acl
.RS 4
Add the entries specified to the ACL\&. Existing access control entries are unchanged\&.
.RE
.PP
\-M|\-\-modify acl
.RS 4
Modify the mask value (permissions) for the ACEs specified on the command line\&. An error will be printed for each ACE specified that was not already present in the object\*(Aqs ACL\&.
.RE
.PP
\-D|\-\-delete acl
.RS 4
Delete any ACEs specified on the command line\&. An error will be printed for each ACE specified that was not already present in the object\*(Aqs ACL\&.
.RE
.PP
\-S|\-\-set acl
.RS 4
This command sets the ACL on the object with only what is specified on the command line\&. Any existing ACL is erased\&. Note that the ACL specified must contain at least a revision, type, owner and group for the call to succeed\&.
.RE
.PP
\-C|\-\-chown name
.RS 4
The owner of a file or directory can be changed to the name given using the
\fI\-C\fR
option\&. The name can be a sid in the form S\-1\-x\-y\-z or a name resolved against the server specified in the first argument\&.
.sp
This command is a shortcut for \-M OWNER:name\&.
.RE
.PP
\-G|\-\-chgrp name
.RS 4
The group owner of a file or directory can be changed to the name given using the
\fI\-G\fR
option\&. The name can be a sid in the form S\-1\-x\-y\-z or a name resolved against the server specified n the first argument\&.
.sp
This command is a shortcut for \-M GROUP:name\&.
.RE
.PP
\-I|\-\-inherit allow|remove|copy
.RS 4
Set or unset the windows "Allow inheritable permissions" check box using the
\fI\-I\fR
option\&. To set the check box pass allow\&. To unset the check box pass either remove or copy\&. Remove will remove all inherited acls\&. Copy will copy all the inherited acls\&.
.RE
.PP
\-\-numeric
.RS 4
This option displays all ACL information in numeric format\&. The default is to convert SIDs to names and ACE types and masks to a readable string format\&.
.RE
.PP
\-m|\-\-max\-protocol PROTOCOL_NAME
.RS 4
This allows the user to select the highest SMB protocol level that smbcacls will use to connect to the server\&. By default this is set to NT1, which is the highest available SMB1 protocol\&. To connect using SMB2 or SMB3 protocol, use the strings SMB2 or SMB3 respectively\&. Note that to connect to a Windows 2012 server with encrypted transport selecting a max\-protocol of SMB3 is required\&.
.RE
.PP
\-t|\-\-test\-args
.RS 4
Don\*(Aqt actually do anything, only validate the correctness of the arguments\&.
.RE
.PP
\-\-query\-security\-info FLAGS
.RS 4
The security\-info flags for queries\&.
.RE
.PP
\-\-set\-security\-info FLAGS
.RS 4
The security\-info flags for queries\&.
.RE
.PP
\-\-sddl
.RS 4
Output and input acls in sddl format\&.
.RE
.PP
\-\-domain\-sid SID
.RS 4
SID used for sddl processing\&.
.RE
.SH "ACL FORMAT"
.PP
The format of an ACL is one or more entries separated by either commas or newlines\&. An ACL entry is one of the following:
.PP
.if n \{\
.RS 4
.\}
.nf
 
REVISION:<revision number>
OWNER:<sid or name>
GROUP:<sid or name>
ACL:<sid or name>:<type>/<flags>/<mask>
.fi
.if n \{\
.RE
.\}
.PP
The revision of the ACL specifies the internal Windows NT ACL revision for the security descriptor\&. If not specified it defaults to 1\&. Using values other than 1 may cause strange behaviour\&.
.PP
The owner and group specify the owner and group sids for the object\&. If a SID in the format S\-1\-x\-y\-z is specified this is used, otherwise the name specified is resolved using the server on which the file or directory resides\&.
.PP
ACEs are specified with an "ACL:" prefix, and define permissions granted to an SID\&. The SID again can be specified in S\-1\-x\-y\-z format or as a name in which case it is resolved against the server on which the file or directory resides\&. The type, flags and mask values determine the type of access granted to the SID\&.
.PP
The type can be either ALLOWED or DENIED to allow/deny access to the SID\&. The flags values are generally zero for file ACEs and either 9 or 2 for directory ACEs\&. Some common flags are:
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c

.RE
.sp
.RE
.PP
At present, flags can only be specified as decimal or hexadecimal values\&.
.PP
The mask is a value which expresses the access right granted to the SID\&. It can be given as a decimal or hexadecimal value, or by using one of the following text strings which map to the NT file permissions of the same name\&.

.SH "EXIT STATUS"
.PP
The
smbcacls
program sets the exit status depending on the success or otherwise of the operations performed\&. The exit status may be one of the following values\&.
.PP
If the operation succeeded, smbcacls returns and exit status of 0\&. If
smbcacls
couldn\*(Aqt connect to the specified server, or there was an error getting or setting the ACLs, an exit status of 1 is returned\&. If there was an error parsing any command line arguments, an exit status of 2 is returned\&.
.SH "VERSION"
.PP
This man page is correct for version 4 of the Samba suite\&.
.SH "AUTHOR"
.PP
The original Samba software and related utilities were created by Andrew Tridgell\&. Samba is now developed by the Samba Team as an Open Source project similar to the way the Linux kernel is developed\&.
.PP
smbcacls
was written by Andrew Tridgell and Tim Potter\&.
.PP
The conversion to DocBook for Samba 2\&.2 was done by Gerald Carter\&. The conversion to DocBook XML 4\&.2 for Samba 3\&.0 was done by Alexander Bokovoy\&.
