40 <p>This module provides authentication front-ends such as
41 <code class="module"><a href="../mod/mod_auth_digest.html">mod_auth_digest</a></code> and <code class="module"><a href="../mod/mod_auth_basic.html">mod_auth_basic</a></code>
42 to authenticate users by looking up users in plain text password files.
43 Similar functionality is provided by <code class="module"><a href="../mod/mod_authn_dbm.html">mod_authn_dbm</a></code>.</p>
45 <p>When using <code class="module"><a href="../mod/mod_auth_basic.html">mod_auth_basic</a></code> or
46 <code class="module"><a href="../mod/mod_auth_digest.html">mod_auth_digest</a></code>, this module is invoked via the
47 <code class="directive"><a href="../mod/mod_auth_basic.html#authbasicprovider">AuthBasicProvider</a></code> or
48 <code class="directive"><a href="../mod/mod_auth_digest.html#authdigestprovider">AuthDigestProvider</a></code>

79 <p>The <code class="directive">AuthUserFile</code> directive sets the name
80 of a textual file containing the list of users and passwords for
81 user authentication. <var>File-path</var> is the path to the user
82 file. If it is not absolute, it is treated as relative to the
83 <code class="directive"><a href="../mod/core.html#serverroot">ServerRoot</a></code>.</p>
85 <p>Each line of the user file contains a username followed by
86 a colon, followed by the encrypted password. If the same user
87 ID is defined multiple times, <code class="module"><a href="../mod/mod_authn_file.html">mod_authn_file</a></code> will
88 use the first occurrence to verify the password.</p>
90 <p>The encrypted password format depends on which authentication
91 frontend (e.g. <code class="module"><a href="../mod/mod_auth_basic.html">mod_auth_basic</a></code> or
92 <code class="module"><a href="../mod/mod_auth_digest.html">mod_auth_digest</a></code>) is being used. See <a href="../misc/password_encryptions.html">Password Formats</a> for
95 <p>For <code class="module"><a href="../mod/mod_auth_basic.html">mod_auth_basic</a></code>, use the utility <code class="program"><a href="../programs/htpasswd.html">htpasswd</a></code>
96 which is installed as part of the binary distribution, or which
97 can be found in <code>src/support</code>. See the
98 <a href="../programs/htpasswd.html">man page</a> for more details.
101 <p>Create a password file <code>Filename</code> with
102 <code>username</code> as the initial ID. It will prompt for
105 <div class="example"><p><code>
106 htpasswd -c Filename username
109 <p>Add or modify <code>username2</code> in the password file
110 <code>Filename</code>:</p>
112 <div class="example"><p><code>
113 htpasswd Filename username2
116 <p>Note that searching large text files is <em>very</em>
117 inefficient; <code class="directive"><a href="../mod/mod_authn_dbm.html#authdbmuserfile">AuthDBMUserFile</a></code> should be used
120 <p>For <code class="module"><a href="../mod/mod_auth_digest.html">mod_auth_digest</a></code>, use <code class="program"><a href="../programs/htdigest.html">htdigest</a></code>
121 instead. Note that you cannot mix user data for Digest Authentication
122 and Basic Authentication within the same file.</p>
124 <div class="warning"><h3>Security</h3>
125 <p>Make sure that the <code class="directive">AuthUserFile</code> is
126 stored outside the document tree of the web-server. Do
127 <strong>not</strong> put it in the directory that it protects.
128 Otherwise, clients may be able to download the
129 <code class="directive">AuthUserFile</code>.</p>
