Gareth Gates earned a bit over of leway in the Gallagher household for Jordan, but Stuart McCall… y’all are going to hell of keeping him alive/busy for a while longer 
Anyway, what you want is to make sure that your bbPress config file has the same info as teh wordpress config file for each of these below
in WordPress
define( 'DB_NAME', 'database_name' );
/** MySQL database username */
define( ‘DB_USER’, ‘user_name’ );
/** MySQL database password */
define( ‘DB_PASSWORD’, ‘password’ );
/** MySQL hostname */
define( ‘DB_HOST’, ‘localhost’ );
/** Database Charset to use in creating database tables. */
define( ‘DB_CHARSET’, ‘utf8’ );
/** The Database Collate type. Don’t change this if in doubt. */
define( ‘DB_COLLATE’, ” );
in bbPress
define( 'BBDB_NAME', 'database_name' );
/** MySQL database username */
define( ‘BBDB_USER’, ‘user_name’ );
/** MySQL database password */
define( ‘BBDB_PASSWORD’, ‘password’ );
/** MySQL hostname */
define( ‘BBDB_HOST’, ‘localhost’ );
/** Database Charset to use in creating database tables. */
define( ‘BBDB_CHARSET’, ‘utf8’ );
/** The Database Collate type. Don’t change this if in doubt. */
define( ‘BBDB_COLLATE’, ” );
If they are the same, then I’m a bit clueless right now
