.SH "DESCRIPTION"
.PP
This tool is part of the
\fBsamba\fR(7)
suite\&.
.PP
The
\FCsmbcacls\F[]
program manipulates NT Access Control Lists (ACLs) on SMB file shares\&.
.SH "OPTIONS"
.PP
The following options are available to the
\FCsmbcacls\F[]
program\&. The format of ACLs is described in the section ACL FORMAT
.PP
\-a acls
.RS 4
Add the ACLs specified to the ACL list\&. Existing access control entries are unchanged\&.
.RE
.PP
\-M acls
.RS 4
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
.RE
.PP
\-D acls
.RS 4
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\&.
.RE
.PP
\-S acls
.RS 4
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\&.
.RE
.PP
\-U username
.RS 4
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 specified in the
\fBsmb.conf\fR(5)
file is used, or "username%password" or "DOMAIN\eusername%password" and the password and workgroup names are used as provided\&.
.RE
.PP
\-C name
.RS 4
The owner of a file or directory can be changed to the name given using the
\fI\-C\fR
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\&.
.sp
This command is a shortcut for \-M OWNER:name\&.
.RE
.PP
\-G name
.RS 4
The group owner of a file or directory can be changed to the name given using the
\fI\-G\fR
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\&.
.sp
This command is a shortcut for \-M GROUP:name\&.
.RE
.PP
\-\-numeric
.RS 4
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\&.
.RE
.PP
\-t
.RS 4
Don\'t actually do anything, only validate the correctness of the arguments\&.
.RE
.PP
\-h|\-\-help
.RS 4
Print a summary of command line options\&.
.RE
.PP
\-d|\-\-debuglevel=level
.RS 4
\fIlevel\fR
is an integer from 0 to 10\&. The default value if this parameter is not specified is 0\&.
.sp
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\&.
.sp
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\&.
.sp
Note that specifying this parameter here will override the
\m[blue]\fBlog level\fR\m[]
parameter in the
\FCsmb\&.conf\F[]
file\&.
.RE
.PP
\-V
.RS 4
Prints the program version number\&.
.RE
.PP
\-s <configuration file>
.RS 4
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
\FCsmb\&.conf\F[]
for more information\&. The default configuration file name is determined at compile time\&.
.RE
.PP
\-l|\-\-log\-basename=logdirectory
.RS 4
Base directory name for log/debug files\&. The extension
\fB"\&.progname"\fR
will be appended (e\&.g\&. log\&.smbclient, log\&.smbd, etc\&.\&.\&.)\&. The log file is never removed by the client\&.
.RE
.SH "ACL FORMAT"
.PP
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:
.PP
.if n \{\
.RS 4
.\}
.fam C
.ps -1
.nf
.BB lightgray
 
REVISION:<revision number>
OWNER:<sid or name>
GROUP:<sid or name>
ACL:<sid or name>:<type>/<flags>/<mask>
.EB lightgray
.fi
.fam
.ps +1
.if n \{\
.RE
.\}
.PP
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\&.
.PP
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\&.
.PP
ACLs specify permissions granted to the SID\&. This SID again 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\&.
.PP
The type can be either ALLOWED or DENIED to allow/deny 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:
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c

.el \{\

.IP \(bu 2.3

.el \{\
.sp -1

\fB#define SEC_ACE_FLAG_INHERIT_ONLY 0x8\fR
.sp
.RE
.PP
At present flags can only be specified as decimal or hexadecimal values\&.
.PP
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\&.
.sp

.ie n \{\

.SH "EXIT STATUS"
.PP
The
\FCsmbcacls\F[]
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\&.
.PP
If the operation succeeded, smbcacls returns and exit status of 0\&. If
\FCsmbcacls\F[]
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\&.
.SH "VERSION"
.PP
This man page is correct for version 3 of the Samba suite\&.
.SH "AUTHOR"
.PP
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\&.
.PP
\FCsmbcacls\F[]
was written by Andrew Tridgell and Tim Potter\&.
.PP
The conversion to DocBook for Samba 2\&.2 was done by Gerald Carter\&. The conversion to DocBook XML 4\&.2 for Samba 3\&.0 was done by Alexander Bokovoy\&.
