sharesec 1 Samba User Commands 4.7 sharesec Set or get share ACLs sharesec sharename -r, --remove=ACL -m, --modify=ACL -a, --add=ACL -R, --replace=ACLs -D, --delete -v, --view --view-all -M, --machine-sid -F, --force -d, --debuglevel=DEBUGLEVEL -s, --configfile=CONFIGFILE -l, --log-basename=LOGFILEBASE --version -?, --help --usage -S, --setsddl=STRING -V, --viewsddl This tool is part of the samba 7 suite. The sharesec program manipulates share permissions on SMB file shares. 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. &stdarg.help; &stdarg.server.debug; &popt.common.samba; 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 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.

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.
