JAVA LDAP錯誤javax.naming.NamingException：[LDAP：錯誤代碼1-000004DC：LdapErr：DSID-0C09075A

Question

我有一個C＃代碼可以連接到LDAP服務器，並且可以正常運行

可用的C＃代碼如下

        user = "myname@myorg.com";
        string pwd = "secret";

        String uid = "uid=" + user + ",ou=people,dc=myorg,dc=com";
        int empID = 0;
        DirectoryEntry root = new DirectoryEntry("LDAP://myorg.com", user, pwd, AuthenticationTypes.None);
        try
        {
            object connected = root.NativeObject;

            DirectorySearcher search = new DirectorySearcher(root);

            search.Filter = "(&(objectClass=user)(objectCategory=Person))";

            search.PropertiesToLoad.Add("SAMAccountName");
            search.PropertiesToLoad.Add("EmployeeID");

            foreach (System.DirectoryServices.SearchResult resEnt in search.FindAll())
            {
                System.DirectoryServices.DirectoryEntry de = resEnt.GetDirectoryEntry();

                if (de.Properties["employeeID"].Value != null && de.Properties["userPrincipalName"].Value != null)
                {
                    if (user.Equals(de.Properties["userPrincipalName"].Value))
                    {
                        string empIDstr = (string)de.Properties["employeeID"].Value;

                        int.TryParse(empIDstr, out empID);
                        Response.Write("EMp ID is No is "+empID);
                    }

                }
            }
        }
        catch(Exception ex)
        {
            Response.Write("Logon failed");
        }

現在，我試圖在Java中做同樣的事情，因為我有另一個要在Java中開發的應用程序，但是以下代碼引發異常

public class LdapClient {


    public void authenticate(String user, String pwd){

        String uid = "uid=" + user + ",ou=people,dc=myorg,dc=com";

        Hashtable env = new Hashtable();
        env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
        env.put(Context.PROVIDER_URL, "ldap://myorg.com");
        env.put(Context.SECURITY_AUTHENTICATION, "none");
        env.put(Context.SECURITY_PRINCIPAL, uid);
        env.put(Context.SECURITY_CREDENTIALS, pwd);

        try {
            DirContext ctx = new InitialDirContext(env);

            **//THE ERROR COMES AT THE LINE BELOW**
            NamingEnumeration<?> namingEnum = ctx.search("ou=people,dc=myorg,dc=com", "(&(objectclass=user)(objectCategory=Person))", getSimpleSearchControls());
            **strong text**
            while (namingEnum.hasMore ()) {
                SearchResult result = (SearchResult) namingEnum.next ();    
                Attributes attrs = result.getAttributes ();
                System.out.println(attrs.get("cn"));

            } 
            namingEnum.close();
        } catch (Exception e) {
            try {
                e.printStackTrace();
            } catch (Exception e1) {
                e1.printStackTrace();
            }
        }
    }

    private SearchControls getSimpleSearchControls() {
        SearchControls searchControls = new SearchControls();
        searchControls.setSearchScope(SearchControls.SUBTREE_SCOPE);
        String[] attrIDs = {"samAccountName","employeeID"};
        searchControls.setReturningAttributes(attrIDs);
        return searchControls;
    }

}

請幫助我，相應的相同代碼在C＃中有效

我必須在Java中執行此操作，因為我需要開發另一個指向同一LDAP服務器的應用程序。 客戶端必須是Java。 請幫忙

例外情況是，在執行操作（搜索）之前，需要進行身份驗證（綁定）。 如文檔所示，嘗試使用simple身份驗證

// Authenticate as S. User and password "mysecret"
env.put(Context.SECURITY_AUTHENTICATION, "simple");
env.put(Context.SECURITY_PRINCIPAL, "cn=S. User, ou=NewHires, o=JNDITutorial");
env.put(Context.SECURITY_CREDENTIALS, "mysecret");
