IMP RC3 Installation problems

[Ricardo Núñez]

Hello,

I've just installing my first IMP 3.0 RC 'anything'. I think I've
followed horde and imp installation instructions, but I'm receiving PHP
errors.

I want and imap conexion with an 'washington' server and I'll use MySQL
to manage 'prefs', I'd also like Turba working.

In horde.php:
...
$conf['auth']['driver'] = 'imap';
...
$conf['prefs']['driver'] = 'sql';
$conf['prefs']['params'] = array();
$conf['prefs']['params']['phptype'] = 'mysql';
$conf['prefs']['params']['hostspec'] = 'localhost';
$conf['prefs']['params']['username'] = 'horde';
$conf['prefs']['params']['password'] = '';
$conf['prefs']['params']['database'] = 'horde';
$conf['prefs']['params']['table'] = 'horde_prefs';
...
In registry.php:
...
$this->registry['auth']['login'] = 'imp';
$this->registry['auth']['logout'] = 'imp';
...
And edited 'servers.php'

Other question... I don't know how to setup an IMAP login to just a
server (not a list).

Thank you very much,
