我正在尝试根据此处给出的教程将 java 对象绑定为一组属性

//In the main() method of the program
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY,
    "com.sun.jndi.ldap.LdapCtxFactory");
env.put(Context.PROVIDER_URL, "ldap://localhost:10389/o=csRepository");
env.put(Context.OBJECT_FACTORIES, "sample.UserFactory");
 // Create the initial context
DirContext ctx = new InitialDirContext(env);

User usr = new User("Goro");
ctx.bind("cn=Kill Bill, ou=employees", null, usr.getAttributes(""));

我有如下的用户类，

public class User implements DirContext {
    String employer;
    Attributes myAttrs;

    public User(String employer){
          this.employer = employer;
          myAttrs = new BasicAttributes(true);
          Attribute oc = new BasicAttribute("objectclass");
          oc.add("extensibleObject");
          oc.add("top");

          myAttrs.put(oc);
          myAttrs.put("em", employer);
       }

    public Attributes getAttributes(String name) throws NamingException {
        if (!name.equals("")) {
            throw new NameNotFoundException();
        }
        return (Attributes) myAttrs.clone();
    }
    //other methods
}

当试图绑定时，我得到，

javax.naming.directory.NoSuchAttributeException: [LDAP: error code 16
- NO_SUCH_ATTRIBUTE: failed for MessageType : ADD_REQUEST Message ID : 2
    Add Request : Entry
    dn[n]: cn=Kill Bill, ou=employees,o=csRepository

为什么它抱怨 OID em 不存在。

因为它没有。使用extensibleObject使您有权将任何现有属性添加到对象。它不赋予你发明新属性的权利。
