The supplied username and password must be already properly verified by an authentication module, such as <code class="module"><a href="../mod/mod_auth_basic.html">mod_auth_basic</a></code> or <code class="module"><a href="../mod/mod_auth_digest.html">mod_auth_digest</a></code>. <code class="module"><a href="../mod/mod_authz_owner.html">mod_authz_owner</a></code> recognizes two arguments for the <code class="directive"><a href="../mod/core.html#require">Require</a></code> directive, <code>file-owner</code> and <code>file-group</code>, as follows:</p> <dl> <dt><code>file-owner</code></dt> <dd>The supplied web-username must match the system's name for the owner of the file being requested. That is, if the operating system says the requested file is owned by <code>jones</code>, then the username used to access it through the web must be <code>jones</code> as well.</dd> <dt><code>file-group</code></dt> <dd>The name of the system group that owns the file must be present in a group database, which is provided, for example, by <code class="module"><a href="../mod/mod_authz_groupfile.html">mod_authz_groupfile</a></code> or <code class="module"><a href="../mod/mod_authz_dbm.html">mod_authz_dbm</a></code>, and the web-username must be a member of that group. For example, if the operating system says the requested file is owned by (system) group <code>accounts</code>, the group <code>accounts</code> must appear in the group database and the web-username used in the request must be a member of that group.</dd> </dl> <div class="note"><h3>Note</h3> <p>If <code class="module"><a href="../mod/mod_authz_owner.html">mod_authz_owner</a></code> is used in order to authorize a resource that is not actually present in the filesystem (<em>i.e.</em> a virtual resource), it will deny the access.</p> <p>Particularly it will never authorize <a href="../content-negotiation.html#multiviews">content negotiated "MultiViews"</a> resources.</p> </div></div><div id="quickview"><h3 class="directives">Directives</h3><ul id="toc"><li><img alt="" src="../images/down.gif" /> <a href="#authzownerauthoritative">AuthzOwnerAuthoritative</a></li></ul><h3>Topics</h3><ul id="topics"><li><img alt="" src="../images/down.gif" /> <a href="#examples">Configuration Examples</a></li></ul><h3>See also</h3><ul class="seealso"><li><code class="directive"><a href="../mod/core.html#require">Require</a></code></li><li><code class="directive"><a href="../mod/core.html#satisfy">Satisfy</a></code></li></ul></div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div><div class="section"><h2><a name="examples" id="examples">Configuration Examples</a></h2> <h3><a name="examples.file-owner" id="examples.file-owner">Require file-owner</a></h3> <p>Consider a multi-user system running the Apache Web server, with each user having his or her own files in <code>~/public_html/private</code>. Assuming that there is a single <code class="directive"><a href="../mod/mod_authn_dbm.html#authdbmuserfile">AuthDBMUserFile</a></code> database that lists all of their web-usernames, and that these usernames match the system's usernames that actually own the files on the server, then the following stanza would allow only the user himself access to his own files. User <code>jones</code> would not be allowed to access files in <code>/home/smith/public_html/private</code> unless they were owned by <code>jones</code> instead of <code>smith</code>.</p> <div class="example"><p><code> <Directory /home/*/public_html/private><br /> <span class="indent"> AuthType Basic<br /> AuthName MyPrivateFiles<br /> AuthBasicProvider dbm<br /> AuthDBMUserFile /usr/local/apache2/etc/.htdbm-all<br /> Satisfy All<br /> Require file-owner<br /> </span> </Directory> </code></p></div> <h3><a name="examples.file-group" id="examples.file-group">Require file-group</a></h3> <p>Consider a system similar to the one described above, but with some users that share their project files in <code>~/public_html/project-foo</code>. The files are owned by the system group <code>foo</code> and there is a single <code class="directive"><a href="../mod/mod_authz_dbm.html#authdbmgroupfile">AuthDBMGroupFile</a></code> database that contains all of the web-usernames and their group membership, <em>i.e.</em> they must be at least member of a group named <code>foo</code>. So if <code>jones</code> and <code>smith</code> are both member of the group <code>foo</code>, then both will be authorized to access the <code>project-foo</code> directories of each other.</p> <div class="example"><p><code> <Directory /home/*/public_html/project-foo><br /> <span class="indent"> AuthType Basic<br /> AuthName "Project Foo Files"<br /> AuthBasicProvider dbm<br /> <br /> # combined user/group database<br /> AuthDBMUserFile /usr/local/apache2/etc/.htdbm-all<br /> AuthDBMGroupFile /usr/local/apache2/etc/.htdbm-all<br /> <br /> Satisfy All<br /> Require file-group<br /> </span> </Directory> </code></p></div> </div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div><div class="directive-section"><h2><a name="AuthzOwnerAuthoritative" id="AuthzOwnerAuthoritative">AuthzOwnerAuthoritative</a> <a name="authzownerauthoritative" id="authzownerauthoritative">Directive</a></h2><table class="directive"><tr><th><a href="directive-dict.html#Description">Description:</a></th><td>Sets whether authorization will be passed on to lower levelmodules</td></tr><tr><th><a href="directive-dict.html#Syntax">Syntax:</a></th><td><code>AuthzOwnerAuthoritative On|Off</code></td></tr><tr><th><a href="directive-dict.html#Default">Default:</a></th><td><code>AuthzOwnerAuthoritative On</code></td></tr><tr><th><a href="directive-dict.html#Context">Context:</a></th><td>directory, .htaccess</td></tr><tr><th><a href="directive-dict.html#Override">Override:</a></th><td>AuthConfig</td></tr><tr><th><a href="directive-dict.html#Status">Status:</a></th><td>Extension</td></tr><tr><th><a href="directive-dict.html#Module">Module:</a></th><td>mod_authz_owner</td></tr></table> <p>Setting the <code class="directive">AuthzOwnerAuthoritative</code> directive explicitly to <code>Off</code> allows for user authorization to be passed on to lower level modules (as defined in the <code>modules.c</code> files) if:</p> <ul> <li>in the case of <code>file-owner</code> the file-system owner does not match the supplied web-username or could not be determined, or</li> <li>in the case of <code>file-group</code> the file-system group does not contain the supplied web-username or could not be determined.</li> </ul> <p>Note that setting the value to <code>Off</code> also allows the combination of <code>file-owner</code> and <code>file-group</code>, so access will be allowed if either one or the other (or both) match.</p> <p>By default, control is not passed on and an authorization failure will result in an "Authentication Required" reply. Not setting it to <code>Off</code> thus keeps the system secure and forces an NCSA compliant behaviour.</p></div></div><div class="bottomlang"><p><span>Available Languages: </span><a href="../en/mod/mod_authz_owner.html" title="English"> en </a> |<a href="../ja/mod/mod_authz_owner.html" hreflang="ja" rel="alternate" title="Japanese"> ja </a> |<a href="../ko/mod/mod_authz_owner.html" hreflang="ko" rel="alternate" title="Korean"> ko </a></p></div><div id="footer"><p class="apache">Copyright 2008 The Apache Software Foundation.<br />Licensed under the <a href="http://www.apache.org/licenses/LICENSE-2.0">Apache License, Version 2.0</a>.</p><p class="menu"><a href="../mod/">Modules</a> | <a href="../mod/directives.html">Directives</a> | <a href="../faq/">FAQ</a> | <a href="../glossary.html">Glossary</a> | <a href="../sitemap.html">Sitemap</a></p></div></body></html>⌨️ 快捷键说明
