				This example uses the JNDI/LDAP service provider to connect to an LDAP server on the local machine. It then performs a search and looks for controls returned with the search responses. 
				    try {
				        LdapContext ctx = new InitialLdapContext(env, null);
				    
				        // Perform search
				        NamingEnumeration answer = ctx.search("ou=People", "(cn=*)", null);
				    
				        // Examine the response controls (if any)
				        process(ctx.getResponseControls());
				    
				        // Enumerate answers
				        while (answer.hasMore()) {
				            SearchResult si = (SearchResult)answer.next();
				    
				            // Examine the response controls (if any)
				            if (si instanceof HasControls) {
				                process(((HasControls)si).getControls());
				            }
				        }
				        // Examine the response controls (if any)
				        process(ctx.getResponseControls());
				    } catch (NamingException e) {
				    }
