$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

//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...";
}
}
