SMBCACLS !!!SMBCACLS NAME SYNOPSIS DESCRIPTION OPTIONS ACL FORMAT EXIT STATUS VERSION AUTHOR ---- !!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 Sambasuite. 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 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 specified 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 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. __-U username__ Specifies a username used to connect to the specified service. The username may be of the form smb.conf'' file is used, or '' __-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: 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: #define SEC_ACE_FLAG_OBJECT_INHERIT 0x1 #define SEC_ACE_FLAG_CONTAINER_INHERIT 0x2 #define SEC_ACE_FLAG_NO_PROPAGATE_INHERIT 0x4 #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. __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 __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 2.2 of the Samba suite. !!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. __smbcacls__ was written by Andrew Tridgell and Tim Potter. The conversion to !DocBook for Samba 2.2 was done by Gerald Carter ----
