~~NOTOC~~
<WRAP important>
Use of ADODB_FETCH_NUM is strongly discouraged because AD records returned in queries may not all contain the same number of fields

== Specification ==
^Driver Name|ldap|
^Data Provider|ldap|
^Status|Active((This driver is actively supported or enhanced by ADOdb project members))|
^Windows|Yes|
^Unix|Perhaps((We have never tried it except against Microsoft LDAP servers from Windows))|
^ADOdb V5|Yes|
^ADOdb V6|Yes|

===== Description =====
From ADOdb Versions 5.22.8 and 5.23.0, the LDAP driver can be used in the same way as all the other drivers. Simply replace the SQL statement with a valid AD Query String

===== Usage =====

You must use standard [[https://ldap.com/ldap-filters/|LDAP filter terms]] rather than SQL statements when executing a query. Any value provided in the //$bindvars// parameter is ignored,
------------------------------------------------------------
<code php>
DEFINE('ADODB_ASSOC_CASE',ADODB_ASSOC_CASE_UPPER);

$db = ADOnewConnection('ldap');

$db->setFetchMode(ADODB_FETCH_ASSOC);

$baseDN   = 'dc=example,dc=com';
$adServer = 'example.com';
$user     = 'adodb@example.com';
$password = 'adodb!';

$db->connect($adServer,$user,$password,$baseDN);

/*
* Find the first 2 records where the given name is adodb
*/
$result = $db->selectLimit('(givenname=adodb)',2);

while ($r = $result->fetchRow())
{
    print_r($r);
    
}
</code>

Returns the following data. Note that some elements may contain **array** or **binary** data. In this example, the 1st record contains 29 columns, and the second 30.

==== URI Connections ====
The **//Server//** definition can be set in the form ''ldap://server-name''. You must use this if you want to:
  - Use an alternate connection port ''ldap:⁄⁄server-name:3389''
  - Use ldap over SSL - ''ldaps:⁄⁄server-name''




===== Connection Parameters =====

The following values may be injected into the connection via the use of [[v5:reference:connection:getrowassoc|setConnectionParameter()]]


^ OPTION_NAME ^ Type ^
| ''LDAP_OPT_DEREF'' | integer |
| ''LDAP_OPT_SIZELIMIT'' | integer |
| ''LDAP_OPT_TIMELIMIT'' | integer |
| ''LDAP_OPT_PROTOCOL_VERSION'' | integer |
| ''LDAP_OPT_ERROR_NUMBER'' | integer |
| ''LDAP_OPT_REFERRALS'' | boolean |
| ''LDAP_OPT_RESTART'' | boolean |
| ''LDAP_OPT_HOST_NAME'' | string |
| ''LDAP_OPT_ERROR_STRING'' | string |
| ''LDAP_OPT_MATCHED_DN'' | string |
| ''LDAP_OPT_SERVER_CONTROLS'' | array |
| ''LDAP_OPT_CLIENT_CONTROLS'' | array |


From ADOdb 5.22.8 and 5.23.0, default values set are as follows

^Parameter^Value^
|LDAP_OPT_PROTOCOL_VERSION|3|
|LDAP_OPT_REFERRALS|0|

These values can be changed with **//setConnectionParameter()//**

The following usage method is deprecated in PHP8.2 and will not work with PHP 8.3. Use **//setConnectionParameter()//** instead. 

<code php>
$LDAP_CONNECT_OPTIONS = Array(
	Array (
		"OPTION_NAME"=>LDAP_OPT_DEREF,
		"OPTION_VALUE"=>2
	),
	Array (
		"OPTION_NAME"=>LDAP_OPT_SIZELIMIT,
		"OPTION_VALUE"=>100
	),
	Array (
		"OPTION_NAME"=>LDAP_OPT_TIMELIMIT,
		"OPTION_VALUE"=>30
	),
	Array (
		"OPTION_NAME"=>,
		"OPTION_VALUE"=>3
	),
	Array (
		"OPTION_NAME"=>LDAP_OPT_ERROR_NUMBER,
		"OPTION_VALUE"=>13
	),
	Array (
		"OPTION_NAME"=>LDAP_OPT_REFERRALS,
		"OPTION_VALUE"=>FALSE
	),
	Array (
		"OPTION_NAME"=>LDAP_OPT_RESTART,
		"OPTION_VALUE"=>FALSE
	)
);
