The UnboundID LDAP SDK for Java is a fast, comprehensive, and easy-to-use Java API for communicating with LDAP directory servers and performing related tasks like reading and writing LDIF, encoding and decoding data using base64 and ASN.1 BER, and performing secure communication. This package contains the Commercial Edition of the LDAP SDK, which includes all of the general-purpose functionality contained in the Standard Edition, plus additional functionality specific to UnboundID server products.

There is a newer version: 3.2.1

/**
 * 
 *   NOTE:  This class is part of the Commercial Edition of the UnboundID
 *   LDAP SDK for Java.  It is not available for use in applications that
 *   include only the Standard Edition of the LDAP SDK, and is not supported for
 *   use in conjunction with non-UnboundID products.
 * 
 * This class provides a request control which may be used to request the server
 * ID of the server that actually processed the associated request.  It may be
 * used for requests sent directly to a Directory Server, but it is more useful
 * when the request will pass through a Directory Proxy Server instance because
 * the corresponding {@link GetServerIDResponseControl} will provide the server
 * ID of the backend server used to process the request.  This server ID may be
 * used in a {@link RouteToServerRequestControl} instance to request that
 * subsequent operations be processed by the same server.  See the documentation
 * for the {@code RouteToServerRequestControl} for an example that demonstrates
 * this.
 * 


 * This control does not have a value.  The criticality may be either
 * {@code true} or {@code false}.
