LDAP_OPT_X_TLS_RANDOM_FILE string PHP 7.1.0
LDAP_OPT_X_TLS_REQUIRE_CERT integer PHP 7.0.5

LDAP_OPT_SERVER_CONTROLS y LDAP_OPT_CLIENT_CONTROLS solicitan una lista de controles, lo que significa que el valor debe ser un array de controles. Un control consiste en un oid identificando el control, un value opcional, y un indicador opcional representado por criticality. En PHP un control es proporcionado por un array que contiene un elemento con la clave oid, una cadena de valor, y dos elementos opcionales. Los elementos opcionales son la clave value con un valor de tipo cadena, y la clave iscritical con un valor de tipo booleano. El valor de la clave iscritical de forma predeterminada es false si no es provisto. Vea » draft-ietf-ldapext-ldap-c-api-xx.txt para más detalles. Vea también el segundo ejemplo a continuación.

newval

El nuevo valor para el option especificado.

Valores devueltos

Devuelve true en caso de éxito o false en caso de error.

Ejemplos

Ejemplo #1 Establecer la versión del protocolo

<?php
// $ds es un identificador de enlace válido para un servidor de directorio
if (ldap_set_option($ds, LDAP_OPT_PROTOCOL_VERSION, 3)) {
echo
"Utilizando LDAPv3";
} else {
echo
"Falló al establcer la versión 3 del protocolo";
}
?>

Ejemplo #2 Establecer controles del servidor

<?php
// $ds es un identificador de enlace válido para un servidor de directorio
// control sin valor
$ctrl1 = array("oid" => "1.2.752.58.10.1", "iscritical" => true);
// iscritical de forma predeterminada está en FALSE
$ctrl2 = array("oid" => "1.2.752.58.1.10", "value" => "magic");
// intentar establecer ambos controles
if (!ldap_set_option($ds, LDAP_OPT_SERVER_CONTROLS, array($ctrl1, $ctrl2))) {
echo
"Falló al establecer los controles del servidor";
}
?>

As john.hallam@compaq.com above mentioned ,one has to set option LDAP_OPT_PROTOCOL_VERSION=3
ldap_set_option($ds,LDAP_OPT_PROTOCOL_VERSION,3);
to use the ldap_rename function.

However, the ldap_set_option() line has to be written immediately after ldap_connect() and before ldap_bind() statements.

Luckily you can turn on debugging before you open a connection:

ldap_set_option(NULL, LDAP_OPT_DEBUG_LEVEL, 7);

This way you at least can see in the logs if the connection fails...

If you want to disable the TLS cert check (e.g. because you are doing an SSH port-forward, and ldaps is pointing to localhost), then you must invoke:

ldap_set_option(NULL, LDAP_OPT_X_TLS_REQUIRE_CERT,0)
*before* calling ldap_connect()

If you try:

$ds = ldap_connect(...)
ldap_set_option($ds, LDAP_OPT_X_TLS_REQUIRE_CERT,0)

then the option won't actually take effect, and the certificate will be checked anyway, and a TLS failure will happen..

The following flags are valid integer values for the LDAP_OPT_DEREF (as taken from the documentation for ldap_read()):

LDAP_DEREF_NEVER (int 0) - (default) aliases are never dereferenced.

LDAP_DEREF_SEARCHING (int 1) - aliases should be dereferenced during the search but not when locating the base object of the search.

LDAP_DEREF_FINDING (int 2) - aliases should be dereferenced when locating the base object but not during the search.

LDAP_DEREF_ALWAYS (int 3) - aliases should be dereferenced always.

Example:
<?php
ldap_set_option
($ds, LDAP_OPT_DEREF, LDAP_DEREF_ALWAYS);
?>

These are defined in the draft C API (presumably from the original LDAP API). See draft-ietf-ldapext-ldap-c-api-xx.txt included in the OpenLDAP source code distribution.

PHP 7.1 added support for configuring the LDAP CA/Cert environment directly, rather than relying on the environment variables. I noticed that a lot of people are having trouble getting this to work.

The correct way is:
$ds=ldap_connect("ldap.google.com");
ldap_set_option(NULL, LDAP_OPT_X_TLS_CERTFILE, "/path/file.crt");
ldap_set_option(NULL, LDAP_OPT_X_TLS_KEYFILE, "/path/file.key");
ldap_set_option($ds, LDAP_OPT_PROTOCOL_VERSION, 3);
ldap_set_option($ds, LDAP_OPT_REFERRALS, 0);
ldap_start_tls($ds);
...
ldap_close($ds);

I have the following code, but you do not rename the cn, that may be?

$TheDN = "cn=Nombre,ou=Addressbook,dc=axia-ldap,dc=net";
$newRDN = "cn=bill";
$newParent = "ou=Addressbook,dc=axia-ldap,dc=net";
ldap_set_option($ds,LDAP_OPT_PROTOCOL_VERSION,3);
$result = ldap_rename($ds, $TheDN, $newRDN, $newParent, TRUE);

To get this to work I had to set the LDAP version to 3 using ldap_set_option. Here is an example that might help:

$TheDN = "cn=john smith,ou=users,dc=acme,dc=com";
$newRDN = "cn=bill brown";
$newParent = "ou=users,dc=acme,dc=com";
ldap_set_option($ds,LDAP_OPT_PROTOCOL_VERSION,3);
@$result = ldap_rename($ds, $TheDN, $newRDN, $newParent, TRUE);

it seems that ldap_set_option returns 1 for bogus ldap_connect -ions also.
ldap_connect always returns a resource (documented in the
comments of ldap_connect) so it is not possible to check if the
ldap server is there or alive or what. and because ldap_set_option
must be between ldap_connect and ldap_bind, there seems to
be no sense in checking the return value.

it is a bit strange that ldap_bind is the first function which can
really check if a ldap resource is usable because it is the third
function in line to use when working with openldap.

<?php
$connect
= ldap_connect("whatever");
$set = ldap_set_option($connect, LDAP_OPT_PROTOCOL_VERSION, 3);
echo
$set;
?>
