[horde] Horde Authentication over OpenLDAP

[luiz at pucrs.br]

Hello

I´m trying to install the Horde in one Solaris 9 box running OpenLDAP and
Courier IMAP Server. In the google and list archives, I´ve found some docs
about to use the LDAP to store prefs of the Horde, but anything about
authentication using OpenLDAP. Is it possible to make it? When I try to log
in with one LDAP user, there are the following error:

"Required 'hostspec' not specified in authentication configuration."

My horde/test.php:

Horde requires the HTML_Common and HTML_Select classes only for Kronolith
1.0 to display forms correctly.

My horde/config/horde.php
<--snip-->
$conf['auth']['driver'] = 'ldap';
$conf['auth']['params'] = array();
<--snip-->
$conf['prefs']['driver'] = 'ldap';
$conf['prefs']['params']['hostspec'] = 'ldap.my.domain';
$conf['prefs']['params']['port'] = '389';
$conf['prefs']['params']['basedn'] = 'dc=my,dc=domain';
$conf['prefs']['params']['uid'] = 'mail';
<--snip-->

I think that I need to define 'hostspec' (and the other LDAP parameters) in
another part of horde.php or another file, but I don´t know where.
Can someone help me?

Thanks (a lot) in advance
