I've recently installed 0.6.0 and am unable to access webmail.  I'm getting the message in roundcubemail: "DATABASE ERROR: CONNECTION FAILED!"  Mail logs indicate "DB Error: _doConnect: [Error message: Access denied for user 'roundcube'@'localhost' (using pasword: YES)] ** mysqli(mysqli)://roundcube:xxx@localhost/roundcubemail in /usr/share/apache2/roundcubemail-0.3.1/program/include/rcube_mdb2.php on line 100 (GET /mail/)"

While debugging I discovered that the database had not been created, so I created the schema and tables using the provided scripts.  I've modified the mysql.db.inc.php to include the properly formatted (password()) version of the roundcube user's password, and I'm still having no luck. 

Any ideas?
