Hi Experts,


Can you please point me on how to handle referrals in the search operation?
I want the logic to follow the referrals so it collects results from all
Active Directory DCs. I get below exception even with followReferrals set
to true.


public List<Group> getAllGroups(String customer, String baseDn) throws
Exception {

        LdapConnectionTemplate connection =
connections.getLdapConnectionTemplate(customer);

        SearchRequest searchRequest = connection.newSearchRequest(baseDn,
"(objectclass=organizationalUnit)", SearchScope.ONELEVEL, GROUP_ATTRIBUTES);

        searchRequest = searchRequest.followReferrals();

        return connection.search(searchRequest, new GroupMapper());

}
