for further mucking with data. This can be of use in ill situations where not all the required massaging can be done on data with SQL by means of stored procedures, but overlays are called too early and cannot be used to make data non LDAP compliant. - only support for bidirectional DN mucking is provided right now - support for other values mucking is planned - write is not completely tested yet - the API could change quite often; don't rely too much on it other cleanup has been added.
