40 <title>DESCRIPTION</title>
42 <para>This tool is part of the <citerefentry><refentrytitle>samba</refentrytitle>
43 <manvolnum>7</manvolnum></citerefentry> suite.</para>
45 <para>The <command>smbcacls</command> program manipulates NT Access Control
46 Lists (ACLs) on SMB file shares. </para>
51 <title>OPTIONS</title>
53 <para>The following options are available to the <command>smbcacls</command> program.
54 The format of ACLs is described in the section ACL FORMAT </para>
59 <term>-a|--add acls</term>
60 <listitem><para>Add the ACLs specified to the ACL list. Existing
61 access control entries are unchanged. </para></listitem>
67 <term>-M|--modify acls</term>
68 <listitem><para>Modify the mask value (permissions) for the ACLs
69 specified on the command line. An error will be printed for each
70 ACL specified that was not already present in the ACL list
77 <term>-D|--delete acls</term>
78 <listitem><para>Delete any ACLs specified on the command line.
79 An error will be printed for each ACL specified that was not
80 already present in the ACL list. </para></listitem>
86 <term>-S|--set acls</term>
87 <listitem><para>This command sets the ACLs on the file with
88 only the ones specified on the command line. All other ACLs are
89 erased. Note that the ACL specified must contain at least a revision,
90 type, owner and group for the call to succeed. </para></listitem>
96 <term>-C|--chown name</term>
97 <listitem><para>The owner of a file or directory can be changed
98 to the name given using the <parameter>-C</parameter> option.
99 The name can be a sid in the form S-1-x-y-z or a name resolved
100 against the server specified in the first argument. </para>
102 <para>This command is a shortcut for -M OWNER:name.
109 <term>-G|--chgrp name</term>
110 <listitem><para>The group owner of a file or directory can
111 be changed to the name given using the <parameter>-G</parameter>
112 option. The name can be a sid in the form S-1-x-y-z or a name
113 resolved against the server specified n the first argument.
116 <para>This command is a shortcut for -M GROUP:name.</para></listitem>
122 <term>-I|--inherit allow|remove|copy</term>
123 <listitem><para>Set or unset the windows "Allow inheritable
124 permissions" check box using the <parameter>-I</parameter>
125 option. To set the check box pass allow. To unset the check
126 box pass either remove or copy. Remove will remove all
127 inherited acls. Copy will copy all the inherited acls.
135 <term>--numeric</term>
136 <listitem><para>This option displays all ACL information in numeric
137 format. The default is to convert SIDs to names and ACE types
138 and masks to a readable string format. </para></listitem>
142 <term>-t|--test-args</term>
144 Don't actually do anything, only validate the correctness of

152 &popt.common.credentials;
158 <title>ACL FORMAT</title>
160 <para>The format of an ACL is one or more ACL entries separated by
161 either commas or newlines. An ACL entry is one of the following: </para>
163 <para><programlisting>
164 REVISION:<revision number>
165 OWNER:<sid or name>
166 GROUP:<sid or name>
167 ACL:<sid or name>:<type>/<flags>/<mask>
168 </programlisting></para>
171 <para>The revision of the ACL specifies the internal Windows
172 NT ACL revision for the security descriptor.
173 If not specified it defaults to 1. Using values other than 1 may
174 cause strange behaviour. </para>
176 <para>The owner and group specify the owner and group sids for the
177 object. If a SID in the format S-1-x-y-z is specified this is used,
178 otherwise the name specified is resolved using the server on which
179 the file or directory resides. </para>
181 <para>ACLs specify permissions granted to the SID. This SID again
182 can be specified in S-1-x-y-z format or as a name in which case
183 it is resolved against the server on which the file or directory
184 resides. The type, flags and mask values determine the type of
185 access granted to the SID. </para>
187 <para>The type can be either ALLOWED or DENIED to allow/deny access
188 to the SID. The flags values are generally zero for file ACLs and
189 either 9 or 2 for directory ACLs. Some common flags are: </para>
192 <listitem><para><constant>#define SEC_ACE_FLAG_OBJECT_INHERIT 0x1</constant></para></listitem>
193 <listitem><para><constant>#define SEC_ACE_FLAG_CONTAINER_INHERIT 0x2</constant></para></listitem>
194 <listitem><para><constant>#define SEC_ACE_FLAG_NO_PROPAGATE_INHERIT 0x4</constant></para></listitem>
195 <listitem><para><constant>#define SEC_ACE_FLAG_INHERIT_ONLY 0x8</constant></para></listitem>
198 <para>At present flags can only be specified as decimal or
199 hexadecimal values.</para>
201 <para>The mask is a value which expresses the access right
202 granted to the SID. It can be given as a decimal or hexadecimal value,
203 or by using one of the following text strings which map to the NT
204 file permissions of the same name. </para>
207 <listitem><para><emphasis>R</emphasis> - Allow read access </para></listitem>
208 <listitem><para><emphasis>W</emphasis> - Allow write access</para></listitem>
209 <listitem><para><emphasis>X</emphasis> - Execute permission on the object</para></listitem>
210 <listitem><para><emphasis>D</emphasis> - Delete the object</para></listitem>
211 <listitem><para><emphasis>P</emphasis> - Change permissions</para></listitem>
212 <listitem><para><emphasis>O</emphasis> - Take ownership</para></listitem>
216 <para>The following combined permissions can be specified:</para>
220 <listitem><para><emphasis>READ</emphasis> - Equivalent to 'RX'
221 permissions</para></listitem>
222 <listitem><para><emphasis>CHANGE</emphasis> - Equivalent to 'RXWD' permissions
224 <listitem><para><emphasis>FULL</emphasis> - Equivalent to 'RWXDPO'
225 permissions</para></listitem>
230 <title>EXIT STATUS</title>
232 <para>The <command>smbcacls</command> program sets the exit status
233 depending on the success or otherwise of the operations performed.
234 The exit status may be one of the following values. </para>
236 <para>If the operation succeeded, smbcacls returns and exit
237 status of 0. If <command>smbcacls</command> couldn't connect to the specified server,
238 or there was an error getting or setting the ACLs, an exit status
239 of 1 is returned. If there was an error parsing any command line
240 arguments, an exit status of 2 is returned. </para>
244 <title>VERSION</title>
246 <para>This man page is correct for version 3 of the Samba suite.</para>
250 <title>AUTHOR</title>
252 <para>The original Samba software and related utilities
253 were created by Andrew Tridgell. Samba is now developed
254 by the Samba Team as an Open Source project similar
255 to the way the Linux kernel is developed.</para>
257 <para><command>smbcacls</command> was written by Andrew Tridgell
258 and Tim Potter.</para>
260 <para>The conversion to DocBook for Samba 2.2 was done
261 by Gerald Carter. The conversion to DocBook XML 4.2 for Samba 3.0 was done
262 by Alexander Bokovoy.</para>
