[horde] login problems redhat 7.3 with mysql

[Jens Baedeker]

Hi,

just searched through the FAQ / documentation. Installed horde as described
in the manual on a
redhat 7.3 system (imap, mysql). The login screen pop up, but i can't log
in. user 'horde' with pass 'horde'
exists in the mysql user table.

-- schnipp horde.php --

// This is an example configuration for a MySQL preference backend.
// The SQL script to setup the preference database is placed in
// horde/scripts/db/prefs.sql.
$conf['prefs']['params']['phptype'] = 'mysql';
$conf['prefs']['params']['hostspec'] = 'localhost';
$conf['prefs']['params']['username'] = 'horde';
$conf['prefs']['params']['password'] = 'horde';
$conf['prefs']['params']['database'] = 'horde';
$conf['prefs']['params']['table'] = 'horde_prefs';
