The New and a New LDAP SDK Release

Today, UnboundID is unveiling a new website, in addition to a revamp of the company’s main site. is the new home for the UnboundID LDAP SDK for Java, but it’s also intended to be a general resource for all things LDAP. It includes information about many other LDAP APIs for a wide range of programming languages, as well as a number of commercial and open source LDAP server offerings. has a lot of information about LDAP, including in-depth descriptions of protocol operations, key data structures like distinguished names and search filters, the LDIF format, and a glossary of LDAP terms. It also provides a pretty comprehensive list of LDAP specifications and reference documents, including RFCs and IETF drafts, as well as result code and OID references.

We’re also releasing a new 2.3.8 version of the UnboundID LDAP SDK for Java. This is a minor release with only a couple of feature enhancements and bug fixes, including:

  • We’ve added a new Filter.simplifyFilter method that can be used to rearrange search filters so that they can be better optimized and processed more efficiently by many directory servers. This primarily involves simplification of the elements inside AND and OR filters, like removing unnecessary nesting (e.g., if an AND filter is nested inside another AND filter, then the elements inside the inner AND filter are moved into the outer filter), getting rid of duplicate elements, and replacing an AND or OR filters containing a single element with just that element. You can optionally re-order the elements inside an AND or an OR filter in a way that will make elements that are generally more efficient to process come before those that are generally less efficient to parse.
  • We’ve added a utility class for working with and comparing object identifiers (OIDs).
  • We fixed a thread-safety bug in the in-memory directory server.
  • The LDAP SDK document now contains information about a number of LDAP-related specifications defined in RFCs and Internet Drafts, as well as result code and OID reference documents.

The new 2.3.8 release of the LDAP SDK is available for download on or from the SourceForge project page. It’s also available in the Maven Central Repository.
