Question

我需要能够通过LDAP服务器查询活动目录，从活动目录中查找已定义的ACTIVE用户列表。

我尝试通过成功连接到我的ldap服务器来完成此操作。在下面的java代码中，当使用accountExpires属性时，我只返回1条记录。我应该返回一个记录列表，每条记录显示ldap服务器上的DISPLAY NAME和MAIL属性。

这是我的代码：

public static void main(String[] args) {
    ADUserAttributes adUserAttributes = new ADUserAttributes();
    adUserAttributes.getLdapContext());
    adUserAttributes.getActiveEmpRecordsList("0", adUserAttributes.getLdapContext());
}

public LdapContext getLdapContext(){
    LdapContext ctx = null;
    try{
        Hashtable env = new Hashtable();
        env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
        env.put(Context.SECURITY_AUTHENTICATION, "Simple");
        env.put(Context.SECURITY_PRINCIPAL, "e~inventory"); 
        env.put(Context.SECURITY_CREDENTIALS, "password");
        env.put(Context.PROVIDER_URL, "ldap://xxxdc01.txh.org");
        ctx = new InitialLdapContext(env, null);
        System.out.println("Connection Successful.");
    } catch(NamingException nex){
        System.out.println("LDAP Connection: FAILED");
        nex.printStackTrace();
    }
    return ctx;
}

private List<String> getActiveEmpRecordsList(String accountExpires, LdapContext ctx) {
List<String> activeEmpAttributes = new ArrayList<String>();
Attributes attrs = null;
try {
    SearchControls constraints = new SearchControls();
    constraints.setSearchScope(SearchControls.SUBTREE_SCOPE);
    String[] attrIDs = {"displayname", "mail"};
    constraints.setReturningAttributes(attrIDs);
    NamingEnumeration answer = ctx.search("DC=txh,DC=org", "accountExpires=" + accountExpires, constraints);
    if (answer.hasMore()) {
        attrs = ((SearchResult) answer.next()).getAttributes();
        int empNameLen = attrs.get("displayname").toString().length();
        int empEmailAddrLen = attrs.get("mail").toString().length();
        activeEmpAttributes.add(attrs.get("displayname").toString().substring(13, empNameLen));
        activeEmpAttributes.add(attrs.get("mail").toString().substring(6, empEmailAddrLen));
        ctx.close();
    }else{
        throw new Exception("Invalid User");
    }
    System.out.println("activeEmpAttributes: " + activeEmpAttributes);
    System.out.println("count: " + activeEmpAttributes.size());
} catch (Exception ex) {
    ex.printStackTrace();
}
return activeEmpAttributes;
 }

您可以使用PrincipalSearcher和“按示例查询”主体进行搜索：

// create your domain context
PrincipalContext ctx = new PrincipalContext(ContextType.Domain);

// define a "query-by-example" principal - here, we search for active UserPrincipals
UserPrincipal qbeUser = new UserPrincipal(ctx);
qbeUser.Enabled = true;

// create your principal searcher passing in the QBE principal    
PrincipalSearcher srch = new PrincipalSearcher(qbeUser);

// find all matches
foreach(var found in srch.FindAll())
{
    // do whatever here - "found" is of type "Principal" - it could be user, group, computer.....          
}

如果您还没有 - 绝对阅读MSDN文章Managing Directory Security Principals in the .NET Framework 3.5，该文章很好地展示了如何充分利用System.DirectoryServices.AccountManagement

中的新功能

您可以在UserPrincipal上指定任何属性，并将其用作PrincipalSearcher的“按示例查询”。
