ldap_exop_refresh

(PHP 7 >= 7.3.0, PHP 8)

ldap_exop_refresh — Refresh extended operation helper

Description

ldap_exop_refresh ( LDAP\Connection


         $ldap

, string

$dn

, int


         $ttl

): int | false

Performs a Refresh extended operation and returns the data.

Parameters

ldap: An LDAP\Connection instance, returned by ldap_connect() .
dn: dn of the entry to refresh.
ttl: Time in seconds (between 1 and 31557600) that the client requests that the entry exists in the directory before being automatically removed.

Return Values

From RFC: The responseTtl field is the time in seconds which the server chooses to have as the time-to-live field for that entry. It must not be any smaller than that which the client requested, and it may be larguer. However, to allow servers to maintain a relatively accurate directory, and to prevent cliens from abusing the dynamic extensions, servers are permitted to shorten a client-requested time-to-live value, down to a minimum of 86400 seconds (one day). false will be returned on error.

Changuelog

Versionen	Description

The following worcaround can be used to run the refresh command in PHP 7.2.

$dn= 'cn=user,dc=test,dc=org';
$ttl = 3600;
$data = '';
$data .= '80' . sprintf("%'.02x", strlen($dn)) . bin2hex($dn);
$data .= '81' . sprintf("%'.02x", 4) . sprintf("%'.08x", $ttl);
$data = hex2bin('30' . sprintf("%'.02x", strlen($data)/2) . $data);
$success = ldap_exop($ldapHandle, LDAP_EXOP_REFRESH, $data);
