[horde] horde authentication

[cyko]

I'm receiving the following error when trying to log into Horde: 

A fatal error has occurred:
Required 'phptype' not specified in authentication configuration.
[line 89 of /usr/local/www/mail/horde/lib/Auth/sql.php]
Details have been logged for the administrator. 

my horde.conf file appears as follows: 

$conf['auth']['driver'] = 'sql';
$conf['prefs']['driver'] = 'sql'; 

$conf['prefs']['params']['phptype'] = 'mysql';
$conf['prefs']['params']['hostspec'] = 'localhost';
$conf['prefs']['params']['username'] = 'horde';
$conf['prefs']['params']['password'] = 'blah';
$conf['prefs']['params']['database'] = 'horde';
$conf['prefs']['params']['table'] = 'horde_prefs'; 

The database was setup properly using .sql file in scripts/db and I can 
connect fine to the database through console. 

Any assistance would be appreciate.  I'd be more than happy to supply more 
information if I've seemed to leave anything important out. 

Thank you.
