Bug #11697

I'm trying to configure the system to work with ldap, but is not 
working. Seems to be a problem in the builder filter.. Basedn 
attribute is being ignored and filter is wrong..

Follow the error, my configure and my LDAP

Configure:
$conf['prefs']['params']['hostspec'] = '127.0.0.1';
$conf['prefs']['params']['port'] = 389;
$conf['prefs']['params']['tls'] = false;
$conf['prefs']['params']['version'] = 3;
$conf['prefs']['params']['binddn'] = 'cn=Admin,o=EMP';
$conf['prefs']['params']['bindpw'] = 'mypass';
$conf['prefs']['params']['bindas'] = 'admin';
$conf['prefs']['params']['basedn'] = 'o=EMP';
$conf['prefs']['params']['scope'] = 'sub';
$conf['prefs']['params']['uid'] = 'uid';
$conf['prefs']['params']['driverconfig'] = 'custom';
$conf['prefs']['driver'] = 'Ldap';
