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.
Share ACLs do not specify an owner or a group, so these fields are
empty.
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
CONTROL:SR|DP
OWNER:
GROUP:
ACL:S-1-1-0:ALLOWED/0x0/FULL
ACL:S-1-5-21-1866488690-1365729215-3963860297-17724:ALLOWED/0x0/FULL

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.
Opportunity
Personal Opportunity - Free software gives you access to billions of dollars of software at no cost. Use this software for your business, personal use or to develop a profitable skill. Access to source code provides access to a level of capabilities/information that companies protect though copyrights. Open source is a core component of the Internet and it is available to you. Leverage the billions of dollars in resources and capabilities to build a career, establish a business or change the world. The potential is endless for those who understand the opportunity.
Business Opportunity - Goldman Sachs, IBM and countless large corporations are leveraging open source to reduce costs, develop products and increase their bottom lines. Learn what these companies know about open source and how open source can give you the advantage.
Free Software
Free Software provides computer programs and capabilities at no cost but more importantly, it provides the freedom to run, edit, contribute to, and share the software. The importance of free software is a matter of access, not price. Software at no cost is a benefit but ownership rights to the software and source code is far more significant.
Free Office Software - The Libre Office suite provides top desktop productivity tools for free. This includes, a word processor, spreadsheet, presentation engine, drawing and flowcharting, database and math applications. Libre Office is available for Linux or Windows.
Free Books
The Free Books Library is a collection of thousands of the most popular public domain books in an online readable format. The collection includes great classical literature and more recent works where the U.S. copyright has expired. These books are yours to read and use without restrictions.
Source Code - Want to change a program or know how it works? Open Source provides the source code for its programs so that anyone can use, modify or learn how to write those programs themselves. Visit the GNU source code repositories to download the source.
Education
Study at Harvard, Stanford or MIT - Open edX provides free online courses from Harvard, MIT, Columbia, UC Berkeley and other top Universities. Hundreds of courses for almost all major subjects and course levels. Open edx also offers some paid courses and selected certifications.
Linux Manual Pages - A man or manual page is a form of software documentation found on Linux/Unix operating systems. Topics covered include computer programs (including library and system calls), formal standards and conventions, and even abstract concepts.
