# ldap_bind

(PHP 3, PHP 4, PHP 5)

ldap_bind -- Bind to LDAP directory

## Description

bool ldap_bind ( resource link_identifier [, string bind_rdn [, string bind_password]] )

Binds to the LDAP directory with specified RDN and password. Returns `TRUE` on success or `FALSE` on failure.

ldap_bind() does a bind operation on the directory. bind_rdn and bind_password are optional. If not specified, anonymous bind is attempted.

Example 1. Using LDAP Bind
`<?php // using ldap bind $ldaprdn = 'uname'; // ldap rdn or dn $ldappass = 'password'; // associated password // connect to ldap server $ldapconn = ldap_connect("ldap.example.com") or die("Could not connect to LDAP server."); if ($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 $ldapconn = ldap_connect("ldap.example.com") or die("Could not connect to LDAP server."); if ($ldapconn) { // binding anonymously $ldapbind = ldap_bind($ldapconn); if ($ldapbind) { echo "LDAP bind anonymous successful..."; } else { echo "LDAP bind anonymous failed..."; } } ?>`
