Thanks Kiran. I'm not very clear how to achieve this using LdapNetworkConnection.
If I understand correctly, I see we've LdapNetworkConnection.search(SearchRequest request) <https://directory.apache.org/api/gen-docs/latest/apidocs/org/apache/directory/ldap/client/api/LdapNetworkConnection.html#search(org.apache.directory.api.ldap.model.message.SearchRequest)>and set the followReferrals on the search request passed here (the way I was doing in my code snippet)? Also, I'm not terribly familiar with how to process SearchCursor and specifically handle referrals (if I've to do this). Will appreciate if you can point to some example code.
