在LDAP Java Query

Question

我有一个java ldap查询，我在其中提取组中存在的用户。但是，我现在需要过滤掉已禁用的帐户。我添加了一个用户过滤器，但这似乎根本没有撤回任何成员。任何帮助表示赞赏。

下面是我当前的java ldap查询。

private LdapContext getTM1users(MbElement parser) throws FileNotFoundException, SQLException, IOException, MbException, NamingException
{
    LdapContext ctx = null;
    MbElement start = null;
    Attributes attrs = null;
    NamingEnumeration answer = null;
    String group = null;
    String location = null;

    Hashtable<String, String> env = new Hashtable<String, String>();
    env.put(Context.INITIAL_CONTEXT_FACTORY, "Factory");
    env.put(Context.SECURITY_AUTHENTICATION, "Simple");
    env.put(Context.SECURITY_PRINCIPAL, "UserID");
    env.put(Context.SECURITY_CREDENTIALS, "Password");
    env.put(Context.PROVIDER_URL, "ldapURL");

    ctx = new InitialLdapContext(env, null);
    SearchControls constraints = new SearchControls();
    constraints.setSearchScope(SearchControls.SUBTREE_SCOPE);
    String[] attrIDs = {"sAMAccountName"};
    constraints.setReturningAttributes(attrIDs);

    Hashtable<String, String> ht = new Hashtable<String, String>();
    ht.put("Agent_Comm", "Agent_Comm");
    ht.put("Elec_Finance", "Elec_Finance");
    ht.put("Freight", "Freight");
    ht.put("Vids", "Vids");

    Set<String> keys = ht.keySet();

    for(String key : keys)
    {
        group = ht.get(key);
        location = key;

        answer = ctx.search("DC=ads,DC=abc,DC=com", "memberOf=CN=" + group + ",OU=ADM,OU=ABC,DC=ads,DC=abc,DC=com (&(objectclass=user)(!(userAccountControl:1.2.840.113556.1.4.803:=2)))", constraints);
        while (answer.hasMore()) 
        {
            attrs = ((SearchResult) answer.next()).getAttributes();
            start = parser.createElementAsFirstChild(MbElement.TYPE_NAME, "user", null);
            start.createElementAsFirstChild(MbElement.TYPE_NAME_VALUE, "userid",attrs.get("sAMAccountName").toString().trim());
            start.createElementAsFirstChild(MbElement.TYPE_NAME_VALUE, "location", location);               
        }
    }
    return ctx;
}
