RoundCube Webmail Authenticating against Open Directory on Mountain Lion 10.8.x

Sorry about taking so long to get back on here working on this. I've switched over to MySQL. I had a hard time because mysql.sock was located under /tmp/ rather than /var/mysql/ but I fixed that by using the following command:

sudo ln -s /tmp/mysql.sock /var/mysql/mysql.sock

Then I reinstalled roundcube. Here is my main.inc.php file:
