ldap_bind — Bind to LDAP directory
ldap_bind ( resource $ldap [, string|null $dn = null [, string|null $password = null ]] ) : bool
Binds to the LDAP directory with specified RDN and password.
ldap
An LDAP link identifier, returned by ldap_connect().
dn
password
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
Returns true on success or false on failure.
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...";
}
}
?>
