[horde] Fatal Error -> DB Error: Connect Failed

[Kevin Davison]

I know this is a generic DB connection message, but it happens as soon
as I choose mysql for the Datatree option.  All I get when going to
horde now is the error message.  I have the data base and it's fine, but
horde isn't connecting to it for some reason.  Do I need to edit the
file /var/www/html/horde/lib/Horde/DataTree/sql.php ?  I noticed on the
first lines of that file there is:

<?php
/**

Do I need to uncomment and fill this out?
