| <h3>Summary</h3> |
| |
| <p>This module provides authentication front-ends such as |
| <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> |
| to authenticate users by looking up users in plain text password files. |
| Similar functionality is provided by <code class="module"><a href="../mod/mod_authn_dbm.html">mod_authn_dbm</a></code>.</p> |
| |
| <p>When using <code class="module"><a href="../mod/mod_auth_basic.html">mod_auth_basic</a></code> or |
| <code class="module"><a href="../mod/mod_auth_digest.html">mod_auth_digest</a></code>, this module is invoked via the |
| <code class="directive"><a href="../mod/mod_auth_basic.html#authbasicprovider">AuthBasicProvider</a></code> or |
| <code class="directive"><a href="../mod/mod_auth_digest.html#authdigestprovider">AuthDigestProvider</a></code> |
| with the <code>file</code> value.</p> |

| </table> |
| <p>The <code class="directive">AuthUserFile</code> 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 |
| <code class="directive"><a href="../mod/core.html#serverroot">ServerRoot</a></code>.</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, <code class="module"><a href="../mod/mod_authn_file.html">mod_authn_file</a></code> will |
| use the first occurrence to verify the password.</p> |
| |
| <p>The encrypted password format depends on which authentication |
| frontend (e.g. <code class="module"><a href="../mod/mod_auth_basic.html">mod_auth_basic</a></code> or |
| <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 |
| more information.</p> |
| |
| <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> |
| which is installed as part of the binary distribution, or which |
| can be found in <code>src/support</code>. 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> |
| |
| <div class="example"><p><code> |
| htpasswd -c Filename username |
| </code></p></div> |
| |
| <p>Add or modify <code>username2</code> in the password file |
| <code>Filename</code>:</p> |
| |
| <div class="example"><p><code> |
| htpasswd Filename username2 |
| </code></p></div> |
| |
| <p>Note that searching large text files is <em>very</em> |
| inefficient; <code class="directive"><a href="../mod/mod_authn_dbm.html#authdbmuserfile">AuthDBMUserFile</a></code> should be used |
| instead.</p> |
| |
| <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> |
| instead. Note that you cannot mix user data for Digest Authentication |
| and Basic Authentication within the same file.</p> |
| |
| <div class="warning"><h3>Security</h3> |
| <p>Make sure that the <code class="directive">AuthUserFile</code> 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 |
| <code class="directive">AuthUserFile</code>.</p> |
