<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>.</p>

<p>Setting the <code class="directive">AuthBasicAuthoritative</code> directive
explicitly to <strong>'off'</strong> allows for both
authentication and authorization to be passed on to lower level
modules (as defined in the <code>Configuration</code> and
<code>modules.c</code> files) if there is <strong>no
userID</strong> or <strong>rule</strong> matching the supplied
userID. If there is a userID and/or rule specified; the usual
password and access checks will be applied and a failure will give
an Authorization Required reply.</p>
<p>So if a userID appears in the database of more than one module;
or if a valid <code class="directive"><a href="../mod/core.html#require">Require</a></code>
directive applies to more than one module; then the first module
will verify the credentials; and no access is passed on;
regardless of the AuthAuthoritative setting.</p>
<p>By default; control is not passed on; and an unknown userID or
rule will result in an Authorization Required reply. Not setting
it thus keeps the system secure; and forces an NCSA compliant
behaviour.</p>
