/**
* This class implements the processing necessary to perform an LDAPv3 modify DN
* operation, which can be used to rename and/or move an entry or subtree in the
* directory. A modify DN request contains the DN of the target entry, the new
* RDN to use for that entry, and a flag which indicates whether to remove the
* current RDN attribute value(s) from the entry. It may optionally contain a
* new superior DN, which will cause the entry to be moved below that new parent
* entry.
*
* Note that some directory servers may not support all possible uses of the
* modify DN operation. In particular, some servers may not support the use of
* a new superior DN, especially if it may cause the entry to be moved to a
* different database or another server. Also, some servers may not support
* renaming or moving non-leaf entries (i.e., entries that have one or more
* subordinates).
*
* {@code ModifyDNRequest} objects are mutable and therefore can be altered and
* re-used for multiple requests. Note, however, that {@code ModifyDNRequest}
* objects are not threadsafe and therefore a single {@code ModifyDNRequest}
* object instance should not be used to process multiple requests at the same
* time.
*
*
Example
* The following example demonstrates the process for performing a modify DN
* operation. In this case, it will rename "ou=People,dc=example,dc=com" to
* "ou=Users,dc=example,dc=com". It will not move the entry below a new parent.
*
* ModifyDNRequest modifyDNRequest =
* new ModifyDNRequest("ou=People,dc=example,dc=com", "ou=Users", true);
* LDAPResult modifyDNResult;
*
* try
* {
* modifyDNResult = connection.modifyDN(modifyDNRequest);
* // If we get here, the delete was successful.
* }
* catch (LDAPException le)
* {
* // The modify DN operation failed.
* modifyDNResult = le.toLDAPResult();
* ResultCode resultCode = le.getResultCode();
* String errorMessageFromServer = le.getDiagnosticMessage();
* }
