  36     <p>This module provides authentication front-ends such as
  37     <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>
  38     to authenticate users by looking up users in plain text password files.
  39     Similar functionality is provided by <code class="module"><a href="../mod/mod_authn_dbm.html">mod_authn_dbm</a></code>.</p>

  74     <p>The <code class="directive">AuthUserFile</code> directive sets the name
  75     of a textual file containing the list of users and passwords for
  76     user authentication. <var>File-path</var> is the path to the user
  77     file. If it is not absolute, it is treated as relative to the
  78     <code class="directive"><a href="../mod/core.html#serverroot">ServerRoot</a></code>.</p>
  79
  80     <p>Each line of the user file contains a username followed by
  81     a colon, followed by the encrypted password. If the same user
  82     ID is defined multiple times, <code class="module"><a href="../mod/mod_authn_file.html">mod_authn_file</a></code> will
  83     use the first occurrence to verify the password.</p>
  84
  85     <p>The utility <code class="program"><a href="../programs/htpasswd.html">htpasswd</a></code>
  86     which is installed as part of the binary distribution, or which
  87     can be found in <code>src/support</code>, is used to maintain
  88     the password file for <em>HTTP Basic Authentication</em>. See the
  89     <a href="../programs/htpasswd.html">man page</a> for more details.
  90     In short:</p>
  91
  92     <p>Create a password file <code>Filename</code> with
  93     <code>username</code> as the initial ID. It will prompt for
  94     the password:</p>
  95
  96     <div class="example"><p><code>
  97       htpasswd -c Filename username
  98     </code></p></div>
  99
 100     <p>Add or modify <code>username2</code> in the password file
 101     <code>Filename</code>:</p>
 102
 103     <div class="example"><p><code>
 104       htpasswd Filename username2
 105     </code></p></div>
 106
 107     <p>Note that searching large text files is <em>very</em>
 108     inefficient; <code class="directive"><a href="../mod/mod_authn_dbm.html#authdbmuserfile">AuthDBMUserFile</a></code> should be used
 109     instead.</p>
 110
 111     <p>If you are using <em>HTTP Digest Authentication</em>, the <code class="program"><a href="../programs/htpasswd.html">htpasswd</a></code> tool is not sufficient.
 112     You have to use <code class="program"><a href="../programs/htdigest.html">htdigest</a></code>
 113     instead. Note that you cannot mix user data for Digest Authentication
 114     and Basic Authentication within the same file.</p>
 115
 116     <div class="warning"><h3>Security</h3>
 117       <p>Make sure that the <code class="directive">AuthUserFile</code> is
 118       stored outside the document tree of the web-server. Do
 119       <strong>not</strong> put it in the directory that it protects.
