 === Incremental Retrieval of Multi-Valued Attributes
-When there are a very large number of attribute values (>1500) for a specific attribute, Active Directory typically refuses to return all these values at once. Instead, the attribute values are returned according to the http://www.watersprings.org/pub/id/draft-kashi-incremental-00.txt[Incremental Retrieval of Multi-valued Properties] method. Doing so requires the calling part to inspect the returned attribute for specific markers and, if necessary, make additional lookup requests until all values are found.

 Spring LDAP's `org.springframework.ldap.core.support.DefaultIncrementalAttributesMapper` helps when working with this kind of attributes, as follows:
