46 <manvolnum>7</manvolnum></citerefentry> suite.</para>
48 <para>The <command>smbcacls</command> program manipulates NT Access Control
49 Lists (ACLs) on SMB file shares. </para>
54 <title>OPTIONS</title>
56 <para>The following options are available to the <command>smbcacls</command> program.
57 The format of ACLs is described in the section ACL FORMAT </para>
62 <term>-a|--add acls</term>
63 <listitem><para>Add the ACLs specified to the ACL list. Existing
64 access control entries are unchanged. </para></listitem>
70 <term>-M|--modify acls</term>
71 <listitem><para>Modify the mask value (permissions) for the ACLs
72 specified on the command line. An error will be printed for each
73 ACL specified that was not already present in the ACL list
80 <term>-D|--delete acls</term>
81 <listitem><para>Delete any ACLs specified on the command line.
82 An error will be printed for each ACL specified that was not
83 already present in the ACL list. </para></listitem>
89 <term>-S|--set acls</term>
90 <listitem><para>This command sets the ACLs on the file with
91 only the ones specified on the command line. All other ACLs are
92 erased. Note that the ACL specified must contain at least a revision,
93 type, owner and group for the call to succeed. </para></listitem>
99 <term>-C|--chown name</term>
100 <listitem><para>The owner of a file or directory can be changed
101 to the name given using the <parameter>-C</parameter> option.
102 The name can be a sid in the form S-1-x-y-z or a name resolved
103 against the server specified in the first argument. </para>
105 <para>This command is a shortcut for -M OWNER:name.
112 <term>-G|--chgrp name</term>
113 <listitem><para>The group owner of a file or directory can
114 be changed to the name given using the <parameter>-G</parameter>
115 option. The name can be a sid in the form S-1-x-y-z or a name
116 resolved against the server specified n the first argument.
119 <para>This command is a shortcut for -M GROUP:name.</para></listitem>
125 <term>-I|--inherit allow|remove|copy</term>
126 <listitem><para>Set or unset the windows "Allow inheritable
127 permissions" check box using the <parameter>-I</parameter>
128 option. To set the check box pass allow. To unset the check
129 box pass either remove or copy. Remove will remove all
130 inherited acls. Copy will copy all the inherited acls.
138 <term>--numeric</term>
139 <listitem><para>This option displays all ACL information in numeric
140 format. The default is to convert SIDs to names and ACE types
141 and masks to a readable string format. </para></listitem>
145 <term>-m|--max-protocol PROTOCOL_NAME</term>
146 <listitem><para>This allows the user to select the
147 highest SMB protocol level that smbcacls will use to
148 connect to the server. By default this is set to
149 NT1, which is the highest available SMB1 protocol.
150 To connect using SMB2 or SMB3 protocol, use the
151 strings SMB2 or SMB3 respectively. Note that to connect
152 to a Windows 2012 server with encrypted transport selecting
153 a max-protocol of SMB3 is required.
158 <term>-t|--test-args</term>
160 Don't actually do anything, only validate the correctness of
166 <term>--query-security-info FLAGS</term>
167 <listitem><para>The security-info flags for queries.

187 <title>ACL FORMAT</title>
189 <para>The format of an ACL is one or more ACL entries separated by
190 either commas or newlines. An ACL entry is one of the following: </para>
192 <para><programlisting>
193 REVISION:<revision number>
194 OWNER:<sid or name>
195 GROUP:<sid or name>
196 ACL:<sid or name>:<type>/<flags>/<mask>
197 </programlisting></para>
200 <para>The revision of the ACL specifies the internal Windows
201 NT ACL revision for the security descriptor.
202 If not specified it defaults to 1. Using values other than 1 may
203 cause strange behaviour. </para>
205 <para>The owner and group specify the owner and group sids for the
206 object. If a SID in the format S-1-x-y-z is specified this is used,
207 otherwise the name specified is resolved using the server on which
208 the file or directory resides. </para>
210 <para>ACLs specify permissions granted to the SID. This SID again
211 can be specified in S-1-x-y-z format or as a name in which case
212 it is resolved against the server on which the file or directory
213 resides. The type, flags and mask values determine the type of
214 access granted to the SID. </para>
216 <para>The type can be either ALLOWED or DENIED to allow/deny access
217 to the SID. The flags values are generally zero for file ACLs and
218 either 9 or 2 for directory ACLs. Some common flags are: </para>
221 <listitem><para><constant>#define SEC_ACE_FLAG_OBJECT_INHERIT 0x1</constant></para></listitem>
222 <listitem><para><constant>#define SEC_ACE_FLAG_CONTAINER_INHERIT 0x2</constant></para></listitem>
223 <listitem><para><constant>#define SEC_ACE_FLAG_NO_PROPAGATE_INHERIT 0x4</constant></para></listitem>
224 <listitem><para><constant>#define SEC_ACE_FLAG_INHERIT_ONLY 0x8</constant></para></listitem>
227 <para>At present flags can only be specified as decimal or
228 hexadecimal values.</para>
230 <para>The mask is a value which expresses the access right
231 granted to the SID. It can be given as a decimal or hexadecimal value,
232 or by using one of the following text strings which map to the NT
233 file permissions of the same name. </para>
236 <listitem><para><emphasis>R</emphasis> - Allow read access </para></listitem>
237 <listitem><para><emphasis>W</emphasis> - Allow write access</para></listitem>
238 <listitem><para><emphasis>X</emphasis> - Execute permission on the object</para></listitem>
239 <listitem><para><emphasis>D</emphasis> - Delete the object</para></listitem>
240 <listitem><para><emphasis>P</emphasis> - Change permissions</para></listitem>
241 <listitem><para><emphasis>O</emphasis> - Take ownership</para></listitem>
245 <para>The following combined permissions can be specified:</para>
249 <listitem><para><emphasis>READ</emphasis> - Equivalent to 'RX'
250 permissions</para></listitem>
251 <listitem><para><emphasis>CHANGE</emphasis> - Equivalent to 'RXWD' permissions
253 <listitem><para><emphasis>FULL</emphasis> - Equivalent to 'RWXDPO'
254 permissions</para></listitem>
259 <title>EXIT STATUS</title>
261 <para>The <command>smbcacls</command> program sets the exit status
262 depending on the success or otherwise of the operations performed.
263 The exit status may be one of the following values. </para>
265 <para>If the operation succeeded, smbcacls returns and exit
266 status of 0. If <command>smbcacls</command> couldn't connect to the specified server,
267 or there was an error getting or setting the ACLs, an exit status
268 of 1 is returned. If there was an error parsing any command line
269 arguments, an exit status of 2 is returned. </para>
273 <title>VERSION</title>
275 <para>This man page is correct for version 3 of the Samba suite.</para>
279 <title>AUTHOR</title>
281 <para>The original Samba software and related utilities
282 were created by Andrew Tridgell. Samba is now developed
283 by the Samba Team as an Open Source project similar
284 to the way the Linux kernel is developed.</para>
286 <para><command>smbcacls</command> was written by Andrew Tridgell
287 and Tim Potter.</para>
289 <para>The conversion to DocBook for Samba 2.2 was done
290 by Gerald Carter. The conversion to DocBook XML 4.2 for Samba 3.0 was done
291 by Alexander Bokovoy.</para>
