37<h3>Summary</h3>
38
39    <p>This module authorizes access to files by comparing the userid used
40    for HTTP authentication (the web userid) with the file-system owner or
41    group of the requested file. 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>

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>

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>. Assuming that there is a single
92      <code class="directive"><a href="/mod/mod_authn_dbm.html#authdbmuserfile">AuthDBMUserFile</a></code> database
93      that lists all of their web-usernames, and that these usernames match
94      the system's usernames that actually own the files on the server, then
95      the following stanza would allow only the user himself access to his
96      own files. User <code>jones</code> would not be allowed to access
97      files in <code>/home/smith/public_html/private</code> unless they
98      were owned by <code>jones</code> instead of <code>smith</code>.</p>

109
110    <h3><a name="examples.file-group" id="examples.file-group">Require file-group</a></h3>
111      <p>Consider a system similar to the one described above, but with
112      some users that share their project files in
113      <code>~/public_html/project-foo</code>. The files are owned by the
114      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
115      contains all of the web-usernames and their group membership,
116      <em>i.e.</em> they must be at least member of a group named
117      <code>foo</code>. So if <code>jones</code> and <code>smith</code>
118      are both member of the group <code>foo</code>, then both will be
119      authorized to access the <code>project-foo</code> directories of
120      each other.</p>
