wpdb-phpsessions is a PHP sessions backend that uses the MySQL database (via $wpdb) for storage and management.
In an endeavor to speed WordPress sites up we decided to move all PHP sessions into the database. Check out our extensive PHP Sessions Can Hurt Your WordPress Performance article for more information and caveats.
Drop wpdb-phpsessions.php into your wp-content/plugins/ or wp-content/mu-plugins/ directory and enjoy.
