<summary>
<p>This module provides authentication front-ends such as
<module>mod_auth_digest</module> and <module>mod_auth_basic</module>
to authenticate users by looking up users in plain text password files.
Similar functionality is provided by <module>mod_authn_dbm</module>.</p>
<p>When using <module>mod_auth_basic</module> or
<module>mod_auth_digest</module>, this module is invoked via the
<directive module="mod_auth_basic">AuthBasicProvider</directive> or
<directive module="mod_auth_digest">AuthDigestProvider</directive>
with the <code>file</code> value.</p>

<usage>
<p>The <directive>AuthUserFile</directive> directive sets the name
of a textual file containing the list of users and passwords for
user authentication. <var>File-path</var> is the path to the user
file. If it is not absolute, it is treated as relative to the
<directive module="core">ServerRoot</directive>.</p>
<p>Each line of the user file contains a username followed by
a colon, followed by the encrypted password. If the same user
ID is defined multiple times, <module>mod_authn_file</module> will
use the first occurrence to verify the password.</p>
<p>The utility <a href="/programs/htpasswd.html">htpasswd</a>
which is installed as part of the binary distribution, or which
can be found in <code>src/support</code>, is used to maintain
the password file for <em>HTTP Basic Authentication</em>. See the
<a href="/programs/htpasswd.html">man page</a> for more details.
In short:</p>
<p>Create a password file <code>Filename</code> with
<code>username</code> as the initial ID. It will prompt for
the password:</p>
<example>
htpasswd -c Filename username
</example>
<p>Add or modify <code>username2</code> in the password file
<code>Filename</code>:</p>
<example>
htpasswd Filename username2
</example>
<p>Note that searching large text files is <em>very</em>
inefficient; <directive
module="mod_authn_dbm">AuthDBMUserFile</directive> should be used
instead.</p>
<p>If you are using <em>HTTP Digest Authentication</em>, the <a
href="/programs/htpasswd.html">htpasswd</a> tool is not sufficient.
You have to use <a href="/programs/htdigest.html">htdigest</a>
instead. Note that you cannot mix user data for Digest Authentication
and Basic Authentication within the same file.</p>
<note type="warning"><title>Security</title>
<p>Make sure that the <directive>AuthUserFile</directive> is
stored outside the document tree of the web-server. Do
<strong>not</strong> put it in the directory that it protects.
Otherwise, clients may be able to download the
<directive>AuthUserFile</directive>.</p>
