How do I configure my Web application to authenticate users through the UCLA LDAP server?

More info:

I am using PHP with PEAR Auth and my current connection settings are as follows:

$GLOBALS[‘ldapdsn’] = array( ‘url’ => ‘ldap.ucla.edu’, ‘port’ => ‘389’, ‘version’ => ‘3’, ‘basedn’ => ‘ou=person,dc=ldap,dc=ucla,dc=edu’, ‘binddn’ => ‘’, ’bindpw’ => ‘’, ’attributes’ => array(‘uid’), ‘userattr’ => ‘uid’, ‘userfilter’ => ‘’, ’debug’ => false );

Answer: The public LDAP server cannot be used to authenticate users.
