Here is a patch to fix this issue:

The Zend_Ldap_Ldif_Encoder originally was not designed to handle PHP datatypes and convert them into a LDIF representation. It was designed to convert LDAP data (retrieved from the LDAP e.g.) into LDIF data. A change in this behavior would be a bc-breaking change.

Furthermore it would duplicate conversion code from Zend_Ldap_Attribute into Zend_Ldap_Ldif_Encoder which is undesirable. Zend_Ldap_Attribute currently is the only component for converting PHP datatypes from and to LDAP data representation.

The current planing is to refactor Zend_Ldap_Attribute and put all the conversion code into Zend_Ldap_Converter (which currently is just a container for some low-level conversion methods). Zend_Ldap_Ldif_Encoder could then optionally use Zend_Ldap_Converter to allow for PHP datatypes to be directly converted into LDIF data.

Currently the workaround is to use Zend_Ldap_Attribute:

$data = array();
Zend_Ldap_Attribute::setAttribute($data, "booleanValue", array(true, false));
$ldif = Zend_Ldap_Ldif_Encoder::encode($data);

Should be solved with the new Zend_Ldap_Converter
