String account = "aa"; //用户名
   String password = "123"; //登录密码
String root = "dc=scut,dc=edu,dc=cn"; // root
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
env.put(Context.PROVIDER_URL, "ldap://10.10.10.10:389/" + root);
env.put(Context.SECURITY_AUTHENTICATION, "simple");
env.put(Context.SECURITY_PRINCIPAL, account+"@xxx.com" );
env.put(Context.SECURITY_CREDENTIALS, password);
 
try {
// 链接ldap
ctx = new InitialDirContext(env);
JOptionPane.showMessageDialog(this, "认证成功");
System.out.println("认证成功");
} catch (javax.naming.AuthenticationException e) {
JOptionPane.showMessageDialog(this, "认证失败");
System.out.println("认证失败");
} catch (Exception e) {
JOptionPane.showMessageDialog(this, "认证出错");
