.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 comprises 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 ACEs\&. Copy will copy all the inherited ACEs\&.
.RE
.PP
\-\-propagate\-inheritance
.RS 4
Add, modify, delete or set ACEs on an entire directory tree according to the inheritance flags\&. Refer to the INHERITANCE section for details\&.
.RE
.PP
\-\-save savefile
.RS 4
stores the DACLs in sddl format of the specified file or folder for later use with restore\&. SACLS, owner or integrity labels are not stored\&.
.RE
.PP
\-\-restore savefile
.RS 4
applies the stored DACLS to files in directory\&.
.RE
.PP
\-\-recurse
.RS 4
indicates the operation is performed on directory and all files/directories below\&. (only applies to save option)
.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

.RE
.PP
\-\-domain\-sid SID
.RS 4
SID used for sddl processing\&.
.RE
.PP
\-x|\-\-maximum\-access
.RS 4
When displaying an ACL additionally query the server for effective maximum permissions\&. Note that this is only supported with SMB protocol version 2 or higher\&.
.RE
.PP
\-?|\-\-help
.RS 4
Print a summary of command line options\&.
.RE
.PP
\-\-usage
.RS 4
Display brief usage message\&.
.RE
.PP
\-d|\-\-debuglevel=DEBUGLEVEL
.RS 4
\fIlevel\fR
is an integer from 0 to 10\&. The default value if this parameter is not specified is 1 for client applications\&.
.sp
The higher this value, the more detail will be logged to the log files about the activities of the server\&. At level 0, only critical errors and serious warnings will be logged\&. Level 1 is a reasonable level for day\-to\-day running \- it generates a small amount of information about operations carried out\&.
.sp
Levels above 1 will generate considerable amounts of log data, and should only be used when investigating a problem\&. Levels above 3 are designed for use only by developers and generate HUGE amounts of log data, most of which is extremely cryptic\&.
.sp
Note that specifying this parameter here will override the
\m[blue]\fBlog level\fR\m[]
parameter in the
/etc/samba/smb\&.conf
file\&.
.RE
.PP
\-\-debug\-stdout
.RS 4
This will redirect debug output to STDOUT\&. By default all clients are logging to STDERR\&.
.RE
.PP
\-\-configfile=<configuration file>
.RS 4
The file specified contains the configuration details required by the client\&. The information in this file can be general for client and server or only provide client specific like options such as
\m[blue]\fBclient smb encrypt\fR\m[]\&. See
/etc/samba/smb\&.conf
for more information\&. The default configuration file name is determined at compile time\&.
.RE
.PP
\-\-option=<name>=<value>
.RS 4
Set the
\fBsmb.conf\fR(5)
option "<name>" to value "<value>" from the command line\&. This overrides compiled\-in defaults and options read from the configuration file\&. If a name or a value includes a space, wrap whole \-\-option=name=value into quotes\&.
.RE
.PP
\-l|\-\-log\-basename=logdirectory
.RS 4
Base directory name for log/debug files\&. The extension
\fB"\&.progname"\fR
will be appended (e\&.g\&. log\&.smbclient, log\&.smbd, etc\&.\&.\&.)\&. The log file is never removed by the client\&.
.RE
.PP
\-\-leak\-report
.RS 4
Enable talloc leak reporting on exit\&.
.RE
.PP
\-\-leak\-report\-full
.RS 4
Enable full talloc leak reporting on exit\&.
.RE
.PP
\-V|\-\-version
.RS 4
Prints the program version number\&.
.RE
.PP
\-R|\-\-name\-resolve=NAME\-RESOLVE\-ORDER
.RS 4
This option is used to determine what naming services and in what order to resolve host names to IP addresses\&. The option takes a space\-separated string of different name resolution options\&. The best is to wrap the whole \-\-name\-resolve=NAME\-RESOLVE\-ORDER into quotes\&.
.sp
The options are: "lmhosts", "host", "wins" and "bcast"\&. They cause names to be resolved as follows:
.RS
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
\fBlmhosts\fR: Lookup an IP address in the Samba lmhosts file\&. If the line in lmhosts has no name type attached to the NetBIOS name (see the
\fBlmhosts\fR(5)
for details) then any name type matches for lookup\&.
.RE
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
\fBhost\fR: Do a standard host name to IP address resolution, using the system
/etc/hosts, NIS, or DNS lookups\&. This method of name resolution is operating system dependent, for instance on IRIX or Solaris this may be controlled by the
/etc/nsswitch\&.conf
file)\&. Note that this method is only used if the NetBIOS name type being queried is the 0x20 (server) name type, otherwise it is ignored\&.
.RE
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
\fBwins\fR: Query a name with the IP address listed in the
\fIwins server\fR
parameter\&. If no WINS server has been specified this method will be ignored\&.
.RE
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
\fBbcast\fR: Do a broadcast on each of the known local interfaces listed in the
\fIinterfaces\fR
parameter\&. This is the least reliable of the name resolution methods as it depends on the target host being on a locally connected subnet\&.
.RE
.sp
.RE
If this parameter is not set then the name resolve order defined in the
/etc/samba/smb\&.conf
file parameter (\m[blue]\fBname resolve order\fR\m[]) will be used\&.
.sp
The default order is lmhosts, host, wins, bcast\&. Without this parameter or any entry in the
\m[blue]\fBname resolve order\fR\m[]
parameter of the
/etc/samba/smb\&.conf
file, the name resolution methods will be attempted in this order\&.
.RE
.PP
\-O|\-\-socket\-options=SOCKETOPTIONS
.RS 4
TCP socket options to set on the client socket\&. See the socket options parameter in the
/etc/samba/smb\&.conf
manual page for the list of valid options\&.
.RE
.PP
\-m|\-\-max\-protocol=MAXPROTOCOL
.RS 4
The value of the parameter (a string) is the highest protocol level that will be supported by the client\&.
.sp
Note that specifying this parameter here will override the
\m[blue]\fBclient max protocol\fR\m[]
parameter in the
/etc/samba/smb\&.conf
file\&.
.RE
.PP
\-n|\-\-netbiosname=NETBIOSNAME
.RS 4
This option allows you to override the NetBIOS name that Samba uses for itself\&. This is identical to setting the
\m[blue]\fBnetbios name\fR\m[]
parameter in the
/etc/samba/smb\&.conf
file\&. However, a command line setting will take precedence over settings in
/etc/samba/smb\&.conf\&.
.RE
.PP
\-\-netbios\-scope=SCOPE
.RS 4
This specifies a NetBIOS scope that
nmblookup
will use to communicate with when generating NetBIOS names\&. For details on the use of NetBIOS scopes, see rfc1001\&.txt and rfc1002\&.txt\&. NetBIOS scopes are
\fIvery\fR
rarely used, only set this parameter if you are the system administrator in charge of all the NetBIOS systems you communicate with\&.
.RE
.PP
\-W|\-\-workgroup=WORKGROUP
.RS 4
Set the SMB domain of the username\&. This overrides the default domain which is the domain defined in smb\&.conf\&. If the domain specified is the same as the servers NetBIOS name, it causes the client to log on using the servers local SAM (as opposed to the Domain SAM)\&.
.sp
Note that specifying this parameter here will override the
\m[blue]\fBworkgroup\fR\m[]
parameter in the
/etc/samba/smb\&.conf
file\&.
.RE
.PP
\-r|\-\-realm=REALM
.RS 4
Set the realm for the domain\&.
.sp
Note that specifying this parameter here will override the
\m[blue]\fBrealm\fR\m[]
parameter in the
/etc/samba/smb\&.conf
file\&.
.RE
.PP
\-U|\-\-user=[DOMAIN\e]USERNAME[%PASSWORD]
.RS 4
Sets the SMB username or username and password\&.
.sp
If %PASSWORD is not specified, the user will be prompted\&. The client will first check the
\fBUSER\fR
environment variable (which is also permitted to also contain the password separated by a %), then the
\fBLOGNAME\fR
variable (which is not permitted to contain a password) and if either exists, the value is used\&. If these environmental variables are not found, the username found in a Kerberos Credentials cache may be used\&.
.sp
A third option is to use a credentials file which contains the plaintext of the username and password\&. This option is mainly provided for scripts where the admin does not wish to pass the credentials on the command line or via environment variables\&. If this method is used, make certain that the permissions on the file restrict access from unwanted users\&. See the
\fI\-A\fR
for more details\&.
.sp
Be cautious about including passwords in scripts or passing user\-supplied values onto the command line\&. For security it is better to let the Samba client tool ask for the password if needed, or obtain the password once with
kinit\&.
.sp
While Samba will attempt to scrub the password from the process title (as seen in ps), this is after startup and so is subject to a race\&.
.RE
.PP
\-N|\-\-no\-pass
.RS 4
If specified, this parameter suppresses the normal password prompt from the client to the user\&. This is useful when accessing a service that does not require a password\&.
.sp
Unless a password is specified on the command line or this parameter is specified, the client will request a password\&.
.sp
If a password is specified on the command line and this option is also defined the password on the command line will be silently ignored and no password will be used\&.
.RE
.PP
\-\-password
.RS 4
Specify the password on the commandline\&.
.sp
Be cautious about including passwords in scripts or passing user\-supplied values onto the command line\&. For security it is better to let the Samba client tool ask for the password if needed, or obtain the password once with
kinit\&.
.sp
If \-\-password is not specified, the tool will check the
\fBPASSWD\fR
environment variable, followed by
\fBPASSWD_FD\fR
which is expected to contain an open file descriptor (FD) number\&.
.sp
Finally it will check
\fBPASSWD_FILE\fR
(containing a file path to be opened)\&. The file should only contain the password\&. Make certain that the permissions on the file restrict access from unwanted users!
.sp
While Samba will attempt to scrub the password from the process title (as seen in ps), this is after startup and so is subject to a race\&.
.RE
.PP
\-\-pw\-nt\-hash
.RS 4
The supplied password is the NT hash\&.
.RE
.PP
\-A|\-\-authentication\-file=filename
.RS 4
This option allows you to specify a file from which to read the username and password used in the connection\&. The format of the file is:
.sp
.if n \{\
.RS 4
.\}
.nf
				username = <value>
				password = <value>
				domain   = <value>
			
.fi
.if n \{\
.RE

.sp

.RE
.PP
\-P|\-\-machine\-pass
.RS 4
Use stored machine account password\&.
.RE
.PP
\-\-simple\-bind\-dn=DN
.RS 4
DN to use for a simple bind\&.
.RE
.PP
\-\-use\-kerberos=desired|required|off
.RS 4
This parameter determines whether Samba client tools will try to authenticate using Kerberos\&. For Kerberos authentication you need to use dns names instead of IP addresses when connecting to a service\&.
.sp
Note that specifying this parameter here will override the
\m[blue]\fBclient use kerberos\fR\m[]
parameter in the
/etc/samba/smb\&.conf
file\&.
.RE
.PP
\-\-use\-krb5\-ccache=CCACHE
.RS 4
Specifies the credential cache location for Kerberos authentication\&.
.sp
This will set \-\-use\-kerberos=required too\&.
.RE
.PP
\-\-use\-winbind\-ccache
.RS 4
Try to use the credential cache by winbind\&.
.RE
.PP
\-\-client\-protection=sign|encrypt|off
.RS 4
Sets the connection protection the client tool should use\&.
.sp
Note that specifying this parameter here will override the
\m[blue]\fBclient protection\fR\m[]
parameter in the
/etc/samba/smb\&.conf
file\&.
.sp
In case you need more fine grained control you can use:
\-\-option=clientsmbencrypt=OPTION,
\-\-option=clientipcsigning=OPTION,
\-\-option=clientsigning=OPTION\&.
.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:

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\&.
.PP
The flags field defines how the ACE should be considered when performing inheritance\&.
smbcacls

Per\-ACE inheritance flags can be set in the ACE flags field\&. By default, inheritable ACEs e\&.g\&. those marked for object inheritance (OI) or container inheritance (CI), are not propagated to sub\-files or folders\&. However, with the
