<summary>
<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
<module>mod_auth_digest</module>. This module should
usually be combined with at least one authentication module
such as <module>mod_authn_file</module> and one authorization
module such as <module>mod_authz_user</module>.</p>

<usage>
<p>The <directive>AuthBasicProvider</directive> directive sets
which provider is used to authenticate the users for this location.
The default <code>file</code> provider is implemented
by the <module>mod_authn_file</module> module. Make sure
that the chosen provider module is present in the server.</p>

<p>Providers are implemented by <module>mod_authn_dbm</module>,
<module>mod_authn_file</module>, <module>mod_authn_dbd</module>,
and <module>mod_authnz_ldap</module>.</p>

</contextlist>
<override>AuthConfig</override>
<usage>
<p>Normally, each authorization module listed in <directive
module="mod_auth_basic">AuthBasicProvider</directive> will attempt
to verify the user, and if the user is not found in any provider,
access will be denied. Setting the
<directive>AuthBasicAuthoritative</directive> 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 <module>mod_auth_basic</module> with third-party modules
that are not configured with the <directive
module="mod_auth_basic">AuthBasicProvider</directive>
directive. When using such modules, the order of processing
is determined in the modules' source code and is not configurable.</p>
