无法使用 LDAP 连接从 Java 后端检索 Active Directory 用户 [LDAP：错误代码 32 – 没有此类对象]

Question

我想连接到一个 AD 并按用户过滤以检查它是否存在 (uid)。以后我也要查密码

目前我已经尝试实现一些简单的功能，例如在屏幕上列出所有用户、他们的姓氏和 ID，但没有成功。目标是获取包含所有 uid 的列表，并检查我的网站数据库中是否存在相同的 uid。

我收到此错误：LDAP：错误代码 32 – 没有此类对象

这是我第一次使用 AD，我认为我对 AD 树做错了。

这是我尝试过的代码：

public class ActiveDirectory {

    private Properties properties;
    private DirContext dirContext;
    private boolean conected = false;
    private String Error;


    public ActiveDirectory(String username, String password, String domainController) {

        //Path keystore whith the registred SSL certficate
        String keystorePath = "C:\Program Files\Java\jdk-12.0.2\lib\security\cacerts";
        System.setProperty("javax.net.ssl.keyStore", keystorePath);


        System.setProperty("javax.net.ssl.keyStorePassword", "******");

        properties = new Properties();        
        properties.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
        properties.put(Context.SECURITY_AUTHENTICATION,"simple");

        properties.put(Context.PROVIDER_URL, "LDAPS://kldap.***.***:636");
        properties.put(Context.SECURITY_PRINCIPAL, "uid=blabla,ou=blabla,DC=blabla,DC=blabla");
        properties.put(Context.SECURITY_CREDENTIALS, "******");

        //Initializing active directory LDAP connection
        try {
                    dirContext = new InitialDirContext(properties);
                    String searchFilter = "(objectClass=inetOrgPerson)";
                    String[] requiredAttributes= {"sn", "cn", "employeeNumber"};
                    SearchControls controls = new SearchControls();
                    controls.setSearchScope(SearchControls.SUBTREE_SCOPE);
                    controls.setReturningAttributes(requiredAttributes);
                    NamingEnumeration users = dirContext.search("ou=Users,o=Company", searchFilter, controls);
                    SearchResult searchResult = null;
                    String commonName = null;
                    String surName = null;
                    String employeeNum = null;
                    while (Users.hasMore()) {
                           searchResult = (SearchResult) Users.next();
                           Attributes attr = searchResult.getAttributes();
                           commonName = attr.get("cn").get(0).toString();
                           surName = attr.get("sn").get(0).toString();
                           employeeNum = attr.get("employeeNumber").get(0).toString();
                           System.out.println("Name: " + commonName);
                           System.out.println("Surname: " + surName);
                           System.out.println("Employee number = " + employeeNum);
                    }
                    conected = true;
             } catch (NamingException e) {
                    conected = false;
                    Error = e.getMessage();
                    LOG.severe(e.getMessage());
                    e.printStackTrace();
             }
    }
       public boolean isConected() {
             if (conected) {
                    return true;
             }else {
                    return false;
             }
       }
       public String getError() {
             return Error;
       }
}

已解决！

这是错误的：NamingEnumeration users = dirContext.search("ou=Users,o=Company", searchFilter, controls);

正确的方法是：

NamingEnumeration users = dirContext.search("ou=Users,DC=Blabla,DC=Blabla", searchFilter, controls);
