[英]LDAP AD paging using java
嘗試從 LDAP AD 中的組中獲取成員時,我遇到了一些問題。
1)我需要 1000 的頁面大小,但它返回 1500 個成員(我這邊有什么問題或需要詢問管理員嗎??)
2) Cookie 值始終為 null,我不確定缺少什么。 Cookie 是 null,結果頁面大小是 null
如果您遇到此問題並解決了此問題,請幫助我
Hashtable<String, Object> env = new Hashtable<String, Object>();
LdapContext ctx;
byte[] cookie = null;
try {
env.put(Context.INITIAL_CONTEXT_FACTORY,"com.sun.jndi.ldap.LdapCtxFactory");
env.put(Context.PROVIDER_URL, "ldap://localhost");
env.put(Context.SECURITY_PRINCIPAL,"cn=testaccount");
env.put(Context.SECURITY_CREDENTIALS, "passwd");
env.put(Context.SECURITY_AUTHENTICATION, "simple");
ctx = new InitialLdapContext(env, null);
SearchControls searchCtls = new SearchControls();
String returnedAtts[]={"member"};
searchCtls.setSearchScope(2);
searchCtls.setReturningAttributes(returnedAtts);
ctx.setRequestControls(new Control[] { new PagedResultsControl(1000, false) });
do {
NamingEnumeration answer = ctx.search("", "(&(objectClass=group)(cn=testgroup))", searchCtls);
while (answer.hasMore()) {
SearchResult entry = (SearchResult) answer.next();
String attrsValaues = entry.getAttributes().toString();
System.out.println(attrsValaues);
}
Control[] controls = ctx.getResponseControls();
if (controls != null) {
for (int i = 0; i < controls.length; i++) {
System.out.println(controls[i]);
if (controls[i] instanceof PagedResultsResponseControl) {
PagedResultsResponseControl prrc = (PagedResultsResponseControl) controls[i];
cookie = prrc.getCookie();
}
}
}
ctx.setRequestControls(new Control[] { new PagedResultsControl(1000, cookie, false) });
} while(cookie!=null);
} catch (Exception e) {
e.printStackTrace();
}
我找到了一種不使用 cookie 來獲取用戶的方法
boolean endString = true;
int loopValue = 0;
while (endString) {
int startValue = loopValue * 1000;
int endvalue = (loopValue + 1) * 1000;
SearchControls searchCtls = new SearchControls();
String[] returnedAttrs = new String[1];
String range = startValue + "-" + endvalue;
returnedAttrs[0] = "member;range=" + range;
searchCtls.setSearchScope(SearchControls.SUBTREE_SCOPE);
searchCtls.setReturningAttributes(returnedAttrs);
NamingEnumeration answer = ctx.search("", "(&(objectClass=group)(cn=testgroup))", searchCtls);
while (answer.hasMore()) {
SearchResult entry = (SearchResult) answer.next();
System.out.println(entry.getAttributes());
if (entry.getAttributes().toString().contains("{member;range=" + startValue + "-*")) {
endString = false;
}
}
loopValue++;
}
您可以使用 Spring PagedResultsDirContextProcessor
您需要確保您的 LdapContextSource 已將 setPooled 設置為true
final PagedResultsDirContextProcessor processor = new PagedResultsDirContextProcessor(1000);
while(processor.hasMore()) {
ldap.search(base, filter, controls, mapper, processor);
}
