Enable sizelimit and timelimit in LDAP

[jarbas.junior]

My organization have a OpenLDAP with severals entries (80,000) and a search in OpenLDAP must have a limit for performance.

Its easy.

In the config/main.inc.php add the following lines:

  'sizelimit'     => '0',     // Enables you to limit the count of entries fetched. Setting this to 0 means no limit.
  'timelimit'     => '0',     // Sets the number of seconds how long is spend on the search. Setting this to 0 means no limit. 

In then program/include/rcube_ldap.php alter the following line:

if ($this->ldap_result = @$function($this->conn, $this->prop['base_dn'], $filter, array_values($this->fieldmap), 0, 0 )) {

with the line:

if ($this->ldap_result = @$function($this->conn, $this->prop['base_dn'], $filter, array_values($this->fieldmap), 0, $this->prop['sizelimit'], $this->prop['timelimit'] )) {
