DESCRIPTION

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

       The sharesec program manipulates share permissions on SMB file shares.

OPTIONS

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

       -a|--add=ACL
           Add the ACEs specified to the ACL list.

       -D|--delete
           Delete the entire security descriptor.

       -F|--force
           Force storing the ACL.

       -m|--modify=ACL
           Modify existing ACEs.

       -M|--machine-sid
           Initialize the machine SID.

       -r|--remove=ACL
           Remove ACEs.

       -R|--replace=ACLS
           Overwrite an existing share permission ACL.

       -v|--view
           List a share acl

       --view-all
           List all share acls

       -S|--setsddl=STRING
           Set security descriptor by providing ACL in SDDL format.

       -V|--viewsddl
           List a share acl in SDDL format.

       -?|--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|--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.

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 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 share ACLs.

       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 sharesec 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, sharesec returns and exit status of 0. If sharesec 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.

EXAMPLES

       Add full access for SID S-1-5-21-1866488690-1365729215-3963860297-17724 on share:

                host:~ # sharesec share -a S-1-5-21-1866488690-1365729215-3963860297-17724:ALLOWED/0/FULL

       List all ACEs for share:

                host:~ # sharesec share -v
                REVISION:1
                OWNER:(NULL SID)
                GROUP:(NULL SID)
                ACL:S-1-1-0:ALLOWED/0/0x101f01ff
                ACL:S-1-5-21-1866488690-1365729215-3963860297-17724:ALLOWED/0/FULL
