[horde] $conf['group'] versus $conf['sql']

[Stepan Kadlec]

greetings,
the Horde global configuration allows setup of $conf['group']* options, so I would like to use it for pointing to different mysql database. However it seems those options are ignored and the default $conf['sql']* are taken.

$conf['group']['persistent'] = true;
$conf['group']['username'] = 'horde';
$conf['group']['password'] = '****';
$conf['group']['hostspec'] = 'another.dbhost.tld';
$conf['group']['port'] = 3306;
$conf['group']['protocol'] = 'tcp';
$conf['group']['database'] = 'horde';
$conf['group']['charset'] = 'iso-8859-1';
$conf['group']['splitread'] = false;
$conf['group']['phptype'] = 'mysql';
$conf['group']['driverconfig'] = 'custom';
$conf['group']['driver'] = 'sql';
$conf['group']['cache'] = false;

should this work how I expect? what should I do?

thanks, steve.
