<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>

<description>Sets the authentication provider(s) for this location</description>

<override>AuthConfig</override>

<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>

    <example><title>Example</title>
      &lt;Location /secure&gt;<br />
      <indent>
        AuthType basic<br />
        AuthName "private area"<br />
        AuthBasicProvider  dbm<br />
        AuthDBMType        SDBM<br />
        AuthDBMUserFile    /www/etc/dbmpasswd<br />
        Require            valid-user<br />
      </indent>
      &lt;/Location&gt;
    </example>

    <p> Providers are queried in order until a provider finds a match
    for the requested username, at which point this sole provider will 
    attempt to check the password.  A failure to verify the password does
    not result in control being passed on to subsequent providers.</p>

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

<name>AuthBasicAuthoritative</name>
<description>Sets whether authorization and authentication are passed to
lower level modules</description>
<syntax>AuthBasicAuthoritative On|Off</syntax>
<default>AuthBasicAuthoritative On</default>
<contextlist><context>directory</context><context>.htaccess</context>
</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>
