<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>.</p>

|
||
<p>Setting the <code class="directive">AuthBasicAuthoritative</code> directive
|
||
explicitly to <code>Off</code> allows for both
|
||
authentication and authorization to be passed on to lower level
|
||
modules (as defined in the <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 "Authentication 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 <code class="directive">AuthBasicAuthoritative</code>
|
||
setting.</p>
|
||
|
||
<p>By default control is not passed on and an unknown userID or
|
||
rule will result in an "Authentication Required" reply. Not setting
|
||
it thus keeps the system secure and forces an NCSA compliant
|
||
behaviour.</p>

<p>The <code class="directive">AuthBasicProvider</code> directive sets
|
||
which provider is used to authenticate the users for this location.
|
||
Setting the value to <code>On</code> will choose the default provider
|
||
(<code>file</code>). Since the <code>file</code> provider is implemented
|
||
by the <code class="module"><a href="../mod/mod_authn_file.html">mod_authn_file</a></code> module, you have to make sure,
|
||
that the module is present in the server.</p>
