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 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 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

       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.
