<para>The <command>smbcacls</command> program manipulates NT Access Control
45
Lists (ACLs) on SMB file shares. </para>

<title>OPTIONS</title>
52
<para>The following options are available to the <command>smbcacls</command> program.
53
The format of ACLs is described in the section ACL FORMAT </para>
59
<listitem><para>Add the ACLs specified to the ACL list. Existing
60
access control entries are unchanged. </para></listitem>
67
<listitem><para>Modify the mask value (permissions) for the ACLs
68
specified on the command line. An error will be printed for each
69
ACL specified that was not already present in the ACL list
77
<listitem><para>Delete any ACLs specified on the command line.
78
An error will be printed for each ACL specified that was not
79
already present in the ACL list. </para></listitem>
86
<listitem><para>This command sets the ACLs on the file with
87
only the ones specified on the command line. All other ACLs are
88
erased. Note that the ACL specified must contain at least a revision,
89
type, owner and group for the call to succeed. </para></listitem>
95
<term>-U username</term>
96
<listitem><para>Specifies a username used to connect to the
97
specified service. The username may be of the form "username" in
98
which case the user is prompted to enter in a password and the
99
workgroup specified in the <citerefentry><refentrytitle>smb.conf</refentrytitle>
100
<manvolnum>5</manvolnum></citerefentry> file is
101
used, or "username%password" or "DOMAIN\username%password" and the
102
password and workgroup names are used as provided. </para></listitem>
109
<listitem><para>The owner of a file or directory can be changed
110
to the name given using the <parameter>-C</parameter> option.
111
The name can be a sid in the form S-1-x-y-z or a name resolved
112
against the server specified in the first argument. </para>
114
<para>This command is a shortcut for -M OWNER:name.
122
<listitem><para>The group owner of a file or directory can
123
be changed to the name given using the <parameter>-G</parameter>
124
option. The name can be a sid in the form S-1-x-y-z or a name
125
resolved against the server specified n the first argument.
128
<para>This command is a shortcut for -M GROUP:name.</para></listitem>
134
<term>--numeric</term>
135
<listitem><para>This option displays all ACL information in numeric
136
format. The default is to convert SIDs to names and ACE types
137
and masks to a readable string format. </para></listitem>

<title>ACL FORMAT</title>
158
<para>The format of an ACL is one or more ACL entries separated by
159
either commas or newlines. An ACL entry is one of the following: </para>
161
<para><programlisting>
162
REVISION:<revision number>
163
OWNER:<sid or name>
164
GROUP:<sid or name>
165
ACL:<sid or name>:<type>/<flags>/<mask>
166
</programlisting></para>
169
<para>The revision of the ACL specifies the internal Windows
170
NT ACL revision for the security descriptor.
171
If not specified it defaults to 1. Using values other than 1 may
172
cause strange behaviour. </para>
174
<para>The owner and group specify the owner and group sids for the
175
object. If a SID in the format S-1-x-y-z is specified this is used,
176
otherwise the name specified is resolved using the server on which
177
the file or directory resides. </para>
179
<para>ACLs specify permissions granted to the SID. This SID again
180
can be specified in S-1-x-y-z format or as a name in which case
181
it is resolved against the server on which the file or directory
182
resides. The type, flags and mask values determine the type of
183
access granted to the SID. </para>
185
<para>The type can be either 0 or 1 corresponding to ALLOWED or
186
DENIED access to the SID. The flags values are generally
187
zero for file ACLs and either 9 or 2 for directory ACLs. Some
188
common flags are: </para>
191
<listitem><para><constant>#define SEC_ACE_FLAG_OBJECT_INHERIT 0x1</constant></para></listitem>
192
<listitem><para><constant>#define SEC_ACE_FLAG_CONTAINER_INHERIT 0x2</constant></para></listitem>
193
<listitem><para><constant>#define SEC_ACE_FLAG_NO_PROPAGATE_INHERIT 0x4</constant></para></listitem>
194
<listitem><para><constant>#define SEC_ACE_FLAG_INHERIT_ONLY 0x8</constant></para></listitem>
197
<para>At present flags can only be specified as decimal or
198
hexadecimal values.</para>
200
<para>The mask is a value which expresses the access right
201
granted to the SID. It can be given as a decimal or hexadecimal value,
202
or by using one of the following text strings which map to the NT
203
file permissions of the same name. </para>

<title>EXIT STATUS</title>
231
<para>The <command>smbcacls</command> program sets the exit status
232
depending on the success or otherwise of the operations performed.
233
The exit status may be one of the following values. </para>
235
<para>If the operation succeeded, smbcacls returns and exit
236
status of 0. If <command>smbcacls</command> couldn't connect to the specified server,
237
or there was an error getting or setting the ACLs, an exit status
238
of 1 is returned. If there was an error parsing any command line
239
arguments, an exit status of 2 is returned. </para>
243
<title>VERSION</title>
245
<para>This man page is correct for version 3.0 of the Samba suite.</para>
249
<title>AUTHOR</title>
251
<para>The original Samba software and related utilities
252
were created by Andrew Tridgell. Samba is now developed
253
by the Samba Team as an Open Source project similar
254
to the way the Linux kernel is developed.</para>
256
<para><command>smbcacls</command> was written by Andrew Tridgell
257
and Tim Potter.</para>
259
<para>The conversion to DocBook for Samba 2.2 was done
