smbcacls - Set or get ACLs on an NT file or directory names
SYNOPSIS
smbcacls {//server/share} {/filename} [-D|--delete acls]
[-M|--modify acls] [-a|--add acls] [-S|--set acls]
[-C|--chown name] [-G|--chgrp name] [-I allow|romove|copy]
[--numeric] [-t] [-U username] [-h] [-d]
DESCRIPTION
This tool is part of the samba(7) suite.
The smbcacls program manipulates NT Access Control Lists
(ACLs) on SMB file shares.
OPTIONS
The following options are available to the smbcacls program.
The format of ACLs is described in the section ACL FORMAT
-a|--add acls
Add the ACLs specified to the ACL list. Existing access
control entries are unchanged.
-M|--modify acls
Modify the mask value (permissions) for the ACLs
specified on the command line. An error will be printed
for each ACL specified that was not already present in
the ACL list
-D|--delete acls
Delete any ACLs specified on the command line. An error
will be printed for each ACL specified that was not
already present in the ACL list.
-S|--set acls
This command sets the ACLs on the file with only the
ones specified on the command line. All other ACLs are
erased. Note that the ACL specified must contain at
least a revision, type, owner and group for the call to
succeed.
-C|--chown name
The owner of a file or directory can be changed to the
name given using the -C 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.
This command is a shortcut for -M OWNER:name.
-G|--chgrp name
The group owner of a file or directory can be changed to
the name given using the -G option. The name can be a

User Commands SMBCACLS(1)
sid in the form S-1-x-y-z or a name resolved against the
server specified n the first argument.
This command is a shortcut for -M GROUP:name.
-I|--inherit allow|remove|copy
Set or unset the windows "Allow inheritable permissions"
check box using the -I 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.
--numeric
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.
-t|--test-args
Don't actually do anything, only validate the
correctness of the arguments.
-h|--help
Print a summary of command line options.
-d|--debuglevel=level
level is an integer from 0 to 10. The default value if
this parameter is not specified is 0.
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.
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.
Note that specifying this parameter here will override
the blue]log level] parameter in the smb.conf file.
-V|--version
Prints the program version number.
-s|--configfile <configuration file>
The file specified contains the configuration details
required by the server. The information in this file
includes server-specific information such as what
printcap file to use, as well as descriptions of all the

User Commands SMBCACLS(1)
services that the server is to provide. See smb.conf for
more information. The default configuration file name is
determined at compile time.
-l|--log-basename=logdirectory
Base directory name for log/debug files. The extension
".progname" will be appended (e.g. log.smbclient,
log.smbd, etc...). The log file is never removed by the
client.
-N|--no-pass
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.
Unless a password is specified on the command line or
this parameter is specified, the client will request a
password.
If a password is specified on the command line and this
option is also defined the password on the command line
will be silently ingnored and no password will be used.
-k|--kerberos
Try to authenticate with kerberos. Only useful in an
Active Directory environment.
-C|--use-ccache
Try to use the credentials cached by winbind.
-A|--authentication-file=filename
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
username = <value>
password = <value>
domain = <value>
Make certain that the permissions on the file restrict
access from unwanted users.
-U|--user=username[%password]
Sets the SMB username or username and password.
If %password is not specified, the user will be
prompted. The client will first check the USER
environment variable, then the LOGNAME variable and if
either exists, the string is uppercased. If these
environmental variables are not found, the username
GUEST is used.

User Commands SMBCACLS(1)
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 -A for
more details.
Be cautious about including passwords in scripts. Also,
on many systems the command line of a running process
may be seen via the ps command. To be safe always allow
rpcclient to prompt for a password and type it in
directly.
ACL FORMAT
The format of an ACL is one or more ACL entries separated by
either commas or newlines. An ACL entry is one of the
following:
REVISION:<revision number>
OWNER:<sid or name>
GROUP:<sid or name>
ACL:<sid or name>:<type>/<flags>/<mask>
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.
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.
ACLs specify permissions granted to the SID. This 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.
The type can be either ALLOWED or DENIED to allow/deny
access to the SID. The flags values are generally zero for
file ACLs and either 9 or 2 for directory ACLs. Some common
flags are:
o #define SEC_ACE_FLAG_OBJECT_INHERIT 0x1
o #define SEC_ACE_FLAG_CONTAINER_INHERIT 0x2
o #define SEC_ACE_FLAG_NO_PROPAGATE_INHERIT 0x4
Samba 3.6 Last change: 09/18/2013 4
User Commands SMBCACLS(1)
o #define SEC_ACE_FLAG_INHERIT_ONLY 0x8
At present flags can only be specified as decimal or
hexadecimal values.
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.
o R - Allow read access
o W - Allow write access
o X - Execute permission on the object
o D - Delete the object
o P - Change permissions
o O - Take ownership
The following combined permissions can be specified:
o READ - Equivalent to 'RX' permissions
o CHANGE - Equivalent to 'RXWD' permissions
o FULL - Equivalent to 'RWXDPO' permissions
EXIT STATUS
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.
If the operation succeeded, smbcacls returns and exit status
of 0. If smbcacls couldn't 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.
VERSION
This man page is correct for version 3 of the Samba suite.
