我正在尝试从AD服务器获取所有用户。 AD服务器中有7000个用户,但在运行我的java代码时,它只返回1000个用户名。是否有任何限制,它一次只能获取最多1000个用户? 请问有什么人可以告诉我如何一次获取所有7000个用户。
这是Java代码 -

searchCtls.setSearchScope(SearchControls.SUBTREE_SCOPE);
// specify the LDAP search filter
String searchFilter = "(&(objectCategory=user))";
// Specify the Base for the search
String searchBase = "DC=domain,DC=com";
// initialize counter to total the results
int totalResults = 0;
// Search for objects using the filter
NamingEnumeration<SearchResult> fetchData = ctx.search(searchBase, searchFilter, searchCtls);
// Loop through the search results
while (fetchData.hasMoreElements()) {
SearchResult sr = (SearchResult) fetchData.next();
totalResults++;
String names[] = sr.getName().split(",");
String name[] = names[0].split("=");
usersList.add(name[1]);
}
System.out.println("Total number of users in AD server : " + totalResults);
System.out.println(usersList);
} catch (NamingException e) {
