Advice on how to deal with SEARCH_RESULT_REFERENCE response in SearchCursor

[Carlo.Accorsi]

Hi,
We're trying to use the API with Active Directory.  Sometimes a search result 
includes a SEARCH_RESULT_REFERENCE..
Even though I'm getting my result, I think this is telling me somewhere else I 
can go find it.

I've never encountered this with ApacheDS as a server but in those cases it's a 
single stand alone machine.

Any patterns or ideas about how to correctly handle this case are appreciated.  
Thanks!


Here is the search request..

MessageType : SEARCH_REQUEST
Message ID : 2
    SearchRequest
        baseDn : 'dc=qualitysys,dc=com'
        filter : '(sAMAccountName=test.user)'
        scope : whole subtree
        typesOnly : false
        Size Limit : 1
        Time Limit : 10000
        Deref Aliases : deref Always
        attributes : '*'
org.apache.directory.api.ldap.model.message.SearchRequestImpl@6a8393b3<mailto:org.apache.directory.api.ldap.model.message.SearchRequestImpl@6a8393b3>


Value of Response response = cursor.get();

MessageType : SEARCH_RESULT_REFERENCE
Message ID : 2
    Search Result Reference
        References
            
'ldap://ForestDnsZones.qualitysys.com/DC=ForestDnsZones,DC=qualitysys,DC=com'


Here's the code I'm using.

              List<Entry> lstEntries = new ArrayList<Entry>();
              req.setSizeLimit(limit);
              SearchCursor cursor = connection.search(req);
              try
              {
                     int count = 0;
                     while(cursor.next())
                     {
                           count++;
                           Response response = cursor.get();

                           Entry entry = 
((SearchResultEntry)response).getEntry(); // Exception is thrown here.
                           if (entry != null)
                           {
                                  lstEntries.add(entry);
                           }
                     }
                     SearchResultDone done = cursor.getSearchResultDone();
