Utilities

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 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:

The preceding example parses any returned attribute range markers and makes repeated requests as necessary until all values for all requested attributes have been retrieved.
