Example #1 Whoami extended operation
<?php
$ds = ldap_connect("localhost"); // assuming the LDAP server is on this host
if ($ds) {
// bind with appropriate dn to give update access
$bind = ldap_bind($ds, "cn=root, o=My Company, c=US", "secret");
if (!$bind) {
echo "Unable to bind to LDAP server";
exit;
}
// Call WHOAMI EXOP
$r = ldap_exop($ds, LDAP_EXOP_WHO_AM_I);
// Parse the result object
ldap_parse_exop($ds, $r, $retdata);
// Output: string(31) "dn:cn=root, o=My Company, c=US"
var_dump($retdata);
// Same thing using $retdata parameter
$success = ldap_exop($ds, LDAP_EXOP_WHO_AM_I, NULL, NULL, $retdata, $retoid);
if ($success) {
var_dump($retdata);
}
ldap_close($ds);
} else {
echo "Unable to connect to LDAP server";
