NAME
smbcacls - Set or get ACLs on an NT file or directory names
SYNOPSIS
smbcacls {/server/share} {filename} [-D acls] [-M acls]
[-a acls] [-S acls] [-C name] [-G name] [--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 acls
Add the ACLs specified to the ACL list. Existing access
control entries are unchanged.
-M 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 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 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.
-U username
Specifies a username used to connect to the specified
service. The username may be of the form "username" in
which case the user is prompted to enter in a password
and the workgroup specified in the smb.conf(4) file is
used, or "username%password" or
"DOMAIN\username%password" and the password and
workgroup names are used as provided.
-C 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 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
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.
--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
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 log level parameter in the smb.conf file.
-V
Prints the program version number.
-s
The file specified contains the configuration details
required by the server. The information in this file
includes server-specific information such as what

User Commands SMBCACLS(1)
printcap file to use, as well as descriptions of all the
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.
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:
OWNER:
GROUP:
ACL:://
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 0 or 1 corresponding to ALOWED or
DENIED 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 SECACEFLAGOBJECTINHERIT 0x1
]o #define SECACEFLAGCONTAINERINHERIT 0x2
]o #define SECACEFLAGNOPROPAGATEINHERIT 0x4
]o #define SECACEFLAGINHERITONLY 0x8

User Commands SMBCACLS(1)
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 FUL - 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 3.0 of the Samba suite.
AUTHOR
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.
smbcacls was written by Andrew Tridgell and Tim Potter.

NOTES

Samba(7) delivers the set of four SMF(5) services as can be
seen from the following example:
$ svcs samba wins winbind swat
STATE STIME FMRI
disabled Apr21 svc:/network/samba:default
disabled Apr21 svc:/network/winbind:default
disabled Apr21 svc:/network/wins:default
disabled Apr21 svc:/network/swat:default
where the services are:
"samba"
runs the smbd daemon managing the CIFS sessions
"wins"
runs the nmbd daemon enabling the browsing (WINS)
"winbind"
runs the winbindd daemon making the domain idmap
"swat"
Samba Web Administration Tool is a service providing
access to browser-based Samba administration interface
and on-line documentation. The service runs on software
loopback network interface on port 901/tcp, i.e. opening
"http:/localhost:901/" in browser will access the SWAT
service on local machine.
Please note: SWAT uses HTP Basic Authentication scheme
where user name and passwords are sent over the network in
clear text. In the SWAT case the user name is root.
Transferring such sensitive data is advisable only on the
