If password is not specified or is empty, an anonymous bind is attempted. The dn can also be left empty for an anonymous bind. This is defined in https://tools.ietf.org/html/rfc2251#section-4.2.2

Examples

Example #1 Using LDAP Bind

<?php

// using ldap bind
$ldaprdn = 'uname'; // ldap rdn or dn
$ldappass = 'password'; // associated password

// connect to ldap server
$ldapconn = ldap_connect("ldap://ldap.example.com")
or die(
"Could not connect to LDAP server.");

if (
$ldapconn) {

// binding to ldap server
$ldapbind = ldap_bind($ldapconn, $ldaprdn, $ldappass);

// verify binding
if ($ldapbind) {
echo
"LDAP bind successful...";
} else {
echo
"LDAP bind failed...";
}

}

?>

Example #2 Using LDAP Bind Anonymously

<?php

//using ldap bind anonymously

// connect to ldap server
$ldapconn = ldap_connect("ldap://ldap.example.com")
or die(
"Could not connect to LDAP server.");

if (
$ldapconn) {

// binding anonymously
$ldapbind = ldap_bind($ldapconn);

if (
$ldapbind) {
echo
"LDAP bind anonymous successful...";
} else {
echo
"LDAP bind anonymous failed...";
}
