The supplied username and password 42 must be already properly verified by an authentication module, 43 such as <code class="module"><a href="/mod/mod_auth_basic.html">mod_auth_basic</a></code> or 44 <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> 45 recognizes two arguments for the <code class="directive"><a href="/mod/mod_authz_core.html#require">Require</a></code> directive, <code>file-owner</code> and 46 <code>file-group</code>, as follows:</p> 47 48 <dl> 49 <dt><code>file-owner</code></dt> 50 <dd>The supplied web-username must match the system's name for the 51 owner of the file being requested. That is, if the operating system 52 says the requested file is owned by <code>jones</code>, then the 53 username used to access it through the web must be <code>jones</code> 54 as well.</dd> 55 56 <dt><code>file-group</code></dt> 57 <dd>The name of the system group that owns the file must be present 58 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>, 59 and the web-username must be a member of that group. For example, if 60 the operating system says the requested file is owned by (system) 61 group <code>accounts</code>, the group <code>accounts</code> must 62 appear in the group database and the web-username used in the request 63 must be a member of that group.</dd> 64 </dl> 65 66 <div class="note"><h3>Note</h3> 67 <p>If <code class="module"><a href="/mod/mod_authz_owner.html">mod_authz_owner</a></code> is used in order to authorize 68 a resource that is not actually present in the filesystem 69 (<em>i.e.</em> a virtual resource), it will deny the access.</p> 70 71 <p>Particularly it will never authorize <a href="/content-negotiation.html#multiviews">content negotiated 72 "MultiViews"</a> resources.</p> 73 </div> 74</div> 75<div id="quickview"><h3 class="directives">Directives</h3> 76<p>This module provides no 77 directives.</p> 78<h3>Topics</h3> 79<ul id="topics"> 80<li><img alt="" src="/images/down.gif" /> <a href="#examples">Configuration Examples</a></li> 81</ul><h3>See also</h3> 82<ul class="seealso"> 83<li><code class="directive"><a href="/mod/mod_authz_core.html#require">Require</a></code></li> 84</ul><ul class="seealso"><li><a href="#comments_section">Comments</a></li></ul></div> 85<div class="top"><a href="#page-header"><img alt="top" src="/images/up.gif" /></a></div> 86<div class="section"> 87<h2><a name="examples" id="examples">Configuration Examples</a></h2> 88 89 <h3><a name="examples.file-owner" id="examples.file-owner">Require file-owner</a></h3> 90 <p>Consider a multi-user system running the Apache Web server, with 91 each user having his or her own files in <code>~/public_html/private</code>.
