!!! Overview
This is some [Example code] for working with the [LDAP_SERVER_RANGE_OPTION_OID] for the [MaxValRange] issue within [Microsoft Active Directory]
First, you must determine if your desired attribute is encumbered by the [MaxValRange].
Calling this method will return 0 if there is no requirement for unusual processing or any value greater than 0 will be the rangeStep required to use.
{{{
/**
* We can dynamically get the range step value if we get retrieve all attribute names. The range step will be in an attribute like: member;range=0-1499
*
* @param idv_searchldc
* @param basedn
* @param filter
* @param return_attribute
* @return
* @throws LDAPException
*/
public static int getRangeStepValue(LDAPConnection idv_searchldc, String basedn, String filter, String return_attribute) throws LDAPException
{
SearchRequest searchRequest = new SearchRequest(basedn, SearchScope.BASE, filter, SearchRequest.ALL_USER_ATTRIBUTES);
List<SearchResultEntry> rangedEntries = idv_searchldc.search(searchRequest).getSearchEntries();
for (Iterator<SearchResultEntry> iterator = rangedEntries.iterator(); iterator.hasNext();)
{
SearchResultEntry searchResultEntry = iterator.next();
Collection<Attribute> allAttribute = searchResultEntry.getAttributes();
for (Iterator<Attribute> attributeIterator = allAttribute.iterator(); attributeIterator.hasNext();)
{
Attribute attribute = attributeIterator.next();
log.debug("---> " + attribute.getName());
String rangeCheckAttribute = return_attribute + ";range=0-";
if (attribute.getName().contains(rangeCheckAttribute))
{
int rangeStep = Integer.parseInt(attribute.getName().substring(attribute.getName().lastIndexOf(rangeCheckAttribute) + rangeCheckAttribute.length()));
log.debug("Range Step is: " + rangeStep);
return rangeStep;
}
else
{
return 0; //rangebasedSearchNot Needed
}
}
}
return 0;
}
}}}
The following method will return a List<String> of all values form an Entry which is encumbered by the [MaxValRange]:
You may need to change it to accommodate non-String values.
