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...";
 }
 
 }
 
 ?>
