[imp] horde/imp+... with multidomain ldap setup

Quoting Timo Boettcher <spida at gmx.net>:

I have the same.

I'm assuming that you only have one url for all domains.  Is
that correct?

If it is and the UID is unique you really don't need the
dc=somedomain1 to search, I would think.  Why would the
following configuration example not work for you?
(correcting the values of course:)

$conf['auth']['driver'] = 'ldap';
$conf['auth']['params']['hostspec'] = 'localhost';
$conf['auth']['params']['basedn'] = $basedn;
$conf['auth']['params']['binddn'] = 'cn=manager,' . $basedn;
$conf['auth']['params']['password'] = 'mysecretpassword';
$conf['auth']['params']['uid'] = 'uid';
$conf['auth']['params']['objectclass'] = array('person');

The above config is for horde/conf.php but if it works,
others would be similar, prefs, turba, etc.
