NAME
    smbcacls - Set or get ACLs on an NT file or directory names

SYNOPSIS
    smbcacls  //server/share  filename [ -U username ] [ -A acls ] [ -M
    acls ] [ -D acls ] [ -S acls ]  [ -C name ] [ -G name ] [ -n  ]  [
    -h ]

DESCRIPTION
    This tool is part of the  Samba 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 for-
    mat 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 speci-
    fied 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 speci-
    fied 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 speci-
    fied in the smb.conf 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.

    -n   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.

    -h   Print usage information on the smbcacls program.

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 CWS-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 CWS-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:

    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 val-
    ues.

    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.

    Source project similar to the way the Linux kernel is developed.
