<h3>Summary</h3>
<p>This module provides authentication front-ends such as
<code class="module"><a href="../mod/mod_auth_digest.html">mod_auth_digest</a></code> and <code class="module"><a href="../mod/mod_auth_basic.html">mod_auth_basic</a></code>
to authenticate users by looking up users in SQL tables.
Similar functionality is provided by, for example,
<code class="module"><a href="../mod/mod_authn_file.html">mod_authn_file</a></code>.</p>
<p>This module relies on <code class="module"><a href="../mod/mod_dbd.html">mod_dbd</a></code> to specify
the backend database driver and connection parameters, and
manage the database connections.</p>
<p>When using <code class="module"><a href="../mod/mod_auth_basic.html">mod_auth_basic</a></code> or
<code class="module"><a href="../mod/mod_auth_digest.html">mod_auth_digest</a></code>, this module is invoked via the
<code class="directive"><a href="../mod/mod_auth_basic.html#authbasicprovider">AuthBasicProvider</a></code> or
<code class="directive"><a href="../mod/mod_auth_digest.html#authdigestprovider">AuthDigestProvider</a></code>
with the <code>dbd</code> value.</p>

<h2><a name="example" id="example">Configuration Example</a></h2>
<p>This simple example shows use of this module in the context of
the Authentication and DBD frameworks.</p>
<div class="example"><pre>
#Database Management
#Use the PostgreSQL driver
<code>DBDriver pgsql</code>
#Connection string: database name and login credentials
<code>DBDParams "dbname=htpasswd user=apache password=xxxxxx"</code>
#Parameters for Connection Pool Management
<code>DBDMin 1
DBDKeep 2
DBDMax 10
DBDExptime 60</code>
#Authentication Section
<code><Directory /usr/www/myhost/private></code>
#mod_auth configuration for authn_dbd
<code>AuthType Basic
AuthName "My Server"
AuthBasicProvider dbd</code>
#authz configuration
<code>Require valid-user</code>
#SQL query to verify a user
#(note: DBD drivers recognise both stdio-like %s and native syntax)

The query must take a single string (typically SQL varchar)
