DESCRIPTION
       This tool is part of the samba(7) suite.

       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.

OPTIONS
       The following options are available to the smbcacls program. The format of ACLs
       is described in the section ACL FORMAT

       -a|--add acl
           Add the entries specified to the ACL. Existing access control entries are
           unchanged.

       -M|--modify acl
           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's ACL.

       -D|--delete acl
           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's ACL.

       -S|--set acl
           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.

       -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 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.

       -m|--max-protocol PROTOCOL_NAME
           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.

       -t|--test-args
           Don't actually do anything, only validate the correctness of the arguments.

       --query-security-info FLAGS
           The security-info flags for queries.

       --set-security-info FLAGS
           The security-info flags for queries.

       --sddl
           Output and input acls in sddl format.

       --domain-sid SID
           SID used for sddl processing.

       -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|--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
           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.

       --option=<name>=<value>
           Set the smb.conf(5) option "<name>" to value "<value>" from the command
           line. This overrides compiled-in defaults and options read from the
           configuration file.

       -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.

           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.

       -S|--signing on|off|required
           Set the client signing state.

       -P|--machine-pass
           Use stored machine account password.

       -e|--encrypt
           This command line parameter requires the remote server support the UNIX
           extensions or that the SMB3 protocol has been selected. Requests that the
           connection be encrypted. Negotiates SMB encryption using either SMB3 or
           POSIX extensions via GSSAPI. Uses the given credentials for the encryption
           negotiation (either kerberos or NTLMv1/v2 if given domain/username/password
           triple. Fails the connection if encryption cannot be negotiated.

       --pw-nt-hash
           The supplied password is the NT hash.

       -n|--netbiosname <primary NetBIOS name>
           This option allows you to override the NetBIOS name that Samba uses for
           itself. This is identical to setting the netbios name parameter in the
           smb.conf file. However, a command line setting will take precedence over
           settings in smb.conf.

       -i|--scope <scope>
           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 very rarely used, only set
           this parameter if you are the system administrator in charge of all the
           NetBIOS systems you communicate with.

       -W|--workgroup=domain
           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).

       -O|--socket-options socket options
           TCP socket options to set on the client socket. See the socket options
           parameter in the smb.conf manual page for the list of valid options.

       -?|--help
           Print a summary of command line options.

       --usage
           Display brief usage message.

ACL FORMAT
       The format of an ACL is one or more 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.

       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.

       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:

              •   #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 command line arguments, an exit status of 2 is returned.
