here you need to handle the reference types (as the exception states)
but if you don't want to follow this referral (known as 'chasing') you can
send a special
control to tell the server to return the reference types as
SearchResultEntry types
to do this you need to add the ManageDsaControl
e.x.
ManageDsaITImpl managedsa = new ManageDsaITImpl();
SearchRequest req = new SearchRequestImpl();
req.addControl( managedsa );
then the below shown exception will not occur, but note that you may want
to do this
only if you don't want to chase the referrals
