Find product name and version using JNDI

Question

Is there any consistent way to find the directory servers product name and version using JNDI. Our software is being used with iPlanet 5.1 and SunOne Directory Server and I need to distinguish between them. Currently I use some code (see below) to look for an object under o=Netscape root branch. But the object I am looking for is apparently (so my sys admin tells me) created as part of the administration server install.
public static String[] getNetscapeFamilyDirectoryServerDetails(String ldapHost, int ldapPort, String principalDN, String principalPassword) throws NamingException {
try {
NamingEnumeration result = performLdapQuery("ldap://" + ldapHost + ":" + ldapPort,"o=NetscapeRoot?nsproductname,nsproductversion?sub?(&(objectclass=nsApplication)(cn~=Directory))",principalDN,principalPassword);
if (result.hasMore()) {
SearchResult sr = (SearchResult)result.next();
Attribute attribute = sr.getAttributes().get("nsproductname");
String productName = (String)attribute.get();
attribute = sr.getAttributes().get("nsproductversion");
String productVersion = (String)attribute.get();
return new String[]{productName,productVersion};
catch (Exception e) {
if (e instanceof NamingException) {
throw (NamingException)e;
return null;
}

SELECT i.instance_name, i.host_name, f.release_name RELEASE, i.version, k.patch_level FROM
v$instance i, fnd_product_groups f, fnd_product_installations k WHERE
UPPER(SUBSTR(i.instance_name, 1, 4)) = UPPER(SUBSTR(f.applications_system_name, 1, 4)) AND
k.application_id = '200';
