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(5) file is used, or
"username%password" or "DOMAIN\username%password" and the password and work-
group 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 us-
ing the -G option. The name can be a sid in the form S-1-x-y-z or a name re-
solved 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 for-
mat.
-t Don’t actually do anything, only validate the correctness of the arguments.
-h|--help
Print a summary of command line options.
-V Prints the program version number.
-s <configuration file>
The file specified contains the configuration details required by the serv-
er. The information in this file includes server-specific information such
as what 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 de-
fault configuration file name is determined at compile time.
-d|--debuglevel=level
level is an integer from 0 to 10. The default value if this parameter is not
specified is zero.
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 run-
ning - 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 parameter in the
smb.conf file.
-l|--logfile=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 re-
moved by the client.
ACL FORMAT
The format of an ACL is one or more ACL entries separated by either commas or new-
lines. 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 se-
curity 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 re-
solved 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 ALLOWED 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:
· #define SEC_ACE_FLAG_OBJECT_INHERIT 0x1
· #define SEC_ACE_FLAG_CONTAINER_INHERIT 0x2
· #define SEC_ACE_FLAG_NO_PROPAGATE_INHERIT 0x4
· #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.
· R - Allow read access
· W - Allow write access
· X - Execute permission on the object
· D - Delete the object
· P - Change permissions
· O - Take ownership
The following combined permissions can be specified:
· READ - Equivalent to ’RX’ permissions
· CHANGE - Equivalent to ’RXWD’ permissions
· 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 com-
mand 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.
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.
