36 <title>DESCRIPTION</title>
38 <para>This tool is part of the <citerefentry><refentrytitle>samba</refentrytitle>
39 <manvolnum>7</manvolnum></citerefentry> suite.</para>
41 <para>The <command>smbcacls</command> program manipulates NT Access Control
42 Lists (ACLs) on SMB file shares. </para>
47 <title>OPTIONS</title>
49 <para>The following options are available to the <command>smbcacls</command> program.
50 The format of ACLs is described in the section ACL FORMAT </para>
56 <listitem><para>Add the ACLs specified to the ACL list. Existing
57 access control entries are unchanged. </para></listitem>
64 <listitem><para>Modify the mask value (permissions) for the ACLs
65 specified on the command line. An error will be printed for each
66 ACL specified that was not already present in the ACL list
74 <listitem><para>Delete any ACLs specified on the command line.
75 An error will be printed for each ACL specified that was not
76 already present in the ACL list. </para></listitem>
83 <listitem><para>This command sets the ACLs on the file with
84 only the ones specified on the command line. All other ACLs are
85 erased. Note that the ACL specified must contain at least a revision,
86 type, owner and group for the call to succeed. </para></listitem>
92 <term>-U username</term>
93 <listitem><para>Specifies a username used to connect to the
94 specified service. The username may be of the form "username" in
95 which case the user is prompted to enter in a password and the
96 workgroup specified in the <citerefentry><refentrytitle>smb.conf</refentrytitle>
97 <manvolnum>5</manvolnum></citerefentry> file is
98 used, or "username%password" or "DOMAIN\username%password" and the
99 password and workgroup names are used as provided. </para></listitem>
106 <listitem><para>The owner of a file or directory can be changed
107 to the name given using the <parameter>-C</parameter> option.
108 The name can be a sid in the form S-1-x-y-z or a name resolved
109 against the server specified in the first argument. </para>
111 <para>This command is a shortcut for -M OWNER:name.
119 <listitem><para>The group owner of a file or directory can
120 be changed to the name given using the <parameter>-G</parameter>
121 option. The name can be a sid in the form S-1-x-y-z or a name
122 resolved against the server specified n the first argument.
125 <para>This command is a shortcut for -M GROUP:name.</para></listitem>
131 <term>--numeric</term>
132 <listitem><para>This option displays all ACL information in numeric
133 format. The default is to convert SIDs to names and ACE types
134 and masks to a readable string format. </para></listitem>
140 Don't actually do anything, only validate the correctness of
146 &stdarg.server.debug;
153 <title>ACL FORMAT</title>
155 <para>The format of an ACL is one or more ACL entries separated by
156 either commas or newlines. An ACL entry is one of the following: </para>
158 <para><programlisting>
159 REVISION:<revision number>
160 OWNER:<sid or name>
161 GROUP:<sid or name>
162 ACL:<sid or name>:<type>/<flags>/<mask>
163 </programlisting></para>
166 <para>The revision of the ACL specifies the internal Windows
167 NT ACL revision for the security descriptor.
168 If not specified it defaults to 1. Using values other than 1 may
169 cause strange behaviour. </para>
171 <para>The owner and group specify the owner and group sids for the
172 object. If a SID in the format S-1-x-y-z is specified this is used,
173 otherwise the name specified is resolved using the server on which
174 the file or directory resides. </para>
176 <para>ACLs specify permissions granted to the SID. This SID again
177 can be specified in S-1-x-y-z format or as a name in which case
178 it is resolved against the server on which the file or directory
179 resides. The type, flags and mask values determine the type of
180 access granted to the SID. </para>
182 <para>The type can be either 0 or 1 corresponding to ALLOWED or
183 DENIED access to the SID. The flags values are generally
184 zero for file ACLs and either 9 or 2 for directory ACLs. Some
185 common flags are: </para>
188 <listitem><para><constant>#define SEC_ACE_FLAG_OBJECT_INHERIT 0x1</constant></para></listitem>
189 <listitem><para><constant>#define SEC_ACE_FLAG_CONTAINER_INHERIT 0x2</constant></para></listitem>
190 <listitem><para><constant>#define SEC_ACE_FLAG_NO_PROPAGATE_INHERIT 0x4</constant></para></listitem>
191 <listitem><para><constant>#define SEC_ACE_FLAG_INHERIT_ONLY 0x8</constant></para></listitem>
194 <para>At present flags can only be specified as decimal or
195 hexadecimal values.</para>
197 <para>The mask is a value which expresses the access right
198 granted to the SID. It can be given as a decimal or hexadecimal value,
199 or by using one of the following text strings which map to the NT
200 file permissions of the same name. </para>
203 <listitem><para><emphasis>R</emphasis> - Allow read access </para></listitem>
204 <listitem><para><emphasis>W</emphasis> - Allow write access</para></listitem>
205 <listitem><para><emphasis>X</emphasis> - Execute permission on the object</para></listitem>
206 <listitem><para><emphasis>D</emphasis> - Delete the object</para></listitem>
207 <listitem><para><emphasis>P</emphasis> - Change permissions</para></listitem>
208 <listitem><para><emphasis>O</emphasis> - Take ownership</para></listitem>
212 <para>The following combined permissions can be specified:</para>
216 <listitem><para><emphasis>READ</emphasis> - Equivalent to 'RX'
217 permissions</para></listitem>
218 <listitem><para><emphasis>CHANGE</emphasis> - Equivalent to 'RXWD' permissions
220 <listitem><para><emphasis>FULL</emphasis> - Equivalent to 'RWXDPO'
221 permissions</para></listitem>
226 <title>EXIT STATUS</title>
228 <para>The <command>smbcacls</command> program sets the exit status
229 depending on the success or otherwise of the operations performed.
230 The exit status may be one of the following values. </para>
232 <para>If the operation succeeded, smbcacls returns and exit
233 status of 0. If <command>smbcacls</command> couldn't connect to the specified server,
234 or there was an error getting or setting the ACLs, an exit status
235 of 1 is returned. If there was an error parsing any command line
236 arguments, an exit status of 2 is returned. </para>
240 <title>VERSION</title>
242 <para>This man page is correct for version 3.0 of the Samba suite.</para>
246 <title>AUTHOR</title>
248 <para>The original Samba software and related utilities
249 were created by Andrew Tridgell. Samba is now developed
250 by the Samba Team as an Open Source project similar
251 to the way the Linux kernel is developed.</para>
253 <para><command>smbcacls</command> was written by Andrew Tridgell
254 and Tim Potter.</para>
256 <para>The conversion to DocBook for Samba 2.2 was done
257 by Gerald Carter. The conversion to DocBook XML 4.2 for Samba 3.0 was done
258 by Alexander Bokovoy.</para>
