[horde] ldap + performance

[Andreas Schulze]

Hi again,

My userdatabase is an ldap server. So I have:
$conf['ldap']['hostspec'] = 'ldaps://ldap.example.org';
$conf['ldap']['tls'] = false;
$conf['ldap']['version'] = 3;
$conf['ldap']['binddn'] = 'cn=horde,dc=local';
$conf['ldap']['bindpw'] = 'test';
$conf['ldap']['bindas'] = 'horde';
$conf['ldap']['useldap'] = true;
$conf['auth']['params']['driverconfig'] = 'horde';

I noticed, horde contact the ldap-server on every page requested. Even  
if it's /test.php

51bb907e conn=1069 fd=11 ACCEPT from horde.example.org (IP=[2001...]:636)

That takes only 0.1 sec, but *every* request...

Any suggestions to access ldap really only for authentication purposes?
Thanks
