The ""strange login" page you mention is happening because something  
is stripping out the hostname and being set as NULL in the url on the  
redirect to horde/login.php. I've no idea what that might be in your  
case.

Enable logging (debug/info) in Horde and see if anything "interesting"  
is showing up. If you edit your main "conf.php", you'll want to log to  
a file that has write access for the web user. You COULD start with  
logging priority "INFO" first, then go to "DEBUG" if nothing  
interesting is showing up.

$conf['log']['priority'] = 'DEBUG';
$conf['log']['ident'] = 'HORDE';
$conf['log']['name'] = '/logs/horde.log';
$conf['log']['params']['append'] = true;
$conf['log']['params']['format'] = 'default';
$conf['log']['type'] = 'file';
$conf['log']['enabled'] = true;
