<h3>Summary</h3>
|
||
|
||
<p>This module allows the use of HTTP Basic Authentication to
|
||
restrict access by looking up users in the given providers.
|
||
HTTP Digest Authentication is provided by
|
||
<code class="module"><a href="../mod/mod_auth_digest.html">mod_auth_digest</a></code>. This module should
|
||
usually be combined with at least one authentication module
|
||
such as <code class="module"><a href="../mod/mod_authn_file.html">mod_authn_file</a></code> and one authorization
|
||
module such as <code class="module"><a href="../mod/mod_authz_user.html">mod_authz_user</a></code>.</p>

|
||
<p>Normally, each authorization module listed in <code class="directive"><a href="#authbasicprovider">AuthBasicProvider</a></code> will attempt
|
||
to verify the user, and if the user is not found in any provider,
|
||
access will be denied. Setting the
|
||
<code class="directive">AuthBasicAuthoritative</code> directive explicitly
|
||
to <code>Off</code> allows for both authentication and
|
||
authorization to be passed on to other non-provider-based modules
|
||
if there is <strong>no userID</strong> or <strong>rule</strong>
|
||
matching the supplied userID. This should only be necessary when
|
||
combining <code class="module"><a href="../mod/mod_auth_basic.html">mod_auth_basic</a></code> with third-party modules
|
||
that are not configured with the <code class="directive"><a href="#authbasicprovider">AuthBasicProvider</a></code>
|
||
directive. When using such modules, the order of processing
|
||
is determined in the modules' source code and is not configurable.</p>

<p>The username and password specified are combined into an
|
||
Authorization header, which is passed to the server or service
|
||
behind the webserver. Both the username and password fields are
|
||
interpreted using the <a href="../expr.html">expression parser</a>,
|
||
which allows both the username and password to be set based on
|
||
request parameters.</p>
|
||
|
||
<p>In this example, we pass a fixed username and password to a
|
||
backend server.</p>
|
||
|
||
<div class="example"><h3>Fixed Example</h3><pre class="prettyprint lang-config">
|
||
<Location /demo>
|
||
AuthBasicFake demo demopass
|
||
</Location>
|
||
</pre>
|
||
</div>
|
||
|
||
<p>In this example, we pass the email address extracted from a client
|
||
certificate, extending the functionality of the FakeBasicAuth option
|
||
within the <code class="directive"><a href="../mod/mod_ssl.html#ssloptions">SSLOptions</a></code>
|
||
directive. Like the FakeBasicAuth option, the password is set to the
|
||
fixed string "password".</p>
|
||
|
||
<div class="example"><h3>Certificate Example</h3><pre class="prettyprint lang-config">
|
||
<Location /secure>
|
||
AuthBasicFake %{SSL_CLIENT_S_DN_Email} password
|
||
</Location>
|
||
</pre>
|
||
</div>
|
||
|
||
<p>Extending the above example, we generate a password by hashing the
|
||
email address with a fixed passphrase, and passing the hash to the
|
||
backend server. This can be used to gate into legacy systems that do
|
||
not support client certificates.</p>
|

<div class="example"><h3>Password Example</h3><pre class="prettyprint lang-config">

<p>The <code class="directive">AuthBasicProvider</code> directive sets
|
||
which provider is used to authenticate the users for this location.
|
||
The default <code>file</code> provider is implemented
|
||
by the <code class="module"><a href="../mod/mod_authn_file.html">mod_authn_file</a></code> module. Make sure
|
||
that the chosen provider module is present in the server.</p>
