Java - 未知属性 MS-CHAP-Challenge

Question

我正在关注this java 中的小例子，用于测试 JRadius 客户端。但我不断收到此错误:

Exception in thread "main" net.sf.jradius.exception.UnknownAttributeException: Unknown attribute MS-CHAP-Challenge
at net.sf.jradius.packet.attribute.AttributeFactory.newAttribute(Unknown Source)
at net.sf.jradius.client.auth.MSCHAPv2Authenticator.processRequest(Unknown Source)
at net.sf.jradius.client.RadiusClient.authenticate(Unknown Source)
at lu.restena.zimbra.RestenaAuthenticator.main(RestenaAuthenticator.java:94)

我已经添加了所有 jar 并导入了。

我的代码:

        InetAddress remoteInetAddress = InetAddress.getByName(RADIUSname);
        RadiusClient radiusClient;
        radiusClient = new RadiusClient(
                remoteInetAddress,   // InetAddress - Address of remote RADIUS Server
                sharedSecret); // String - Shared Secret for remote RADIUS Server
        AttributeList attributeList;
        attributeList = new AttributeList();
        attributeList.add(new Attr_UserName(username));
        RadiusAuthenticator auth = RadiusClient.getAuthProtocol("mschapv2");
        RadiusPacket request;
        request = new AccessRequest(radiusClient, attributeList);
        request.addAttribute(new Attr_UserPassword(password));
        RadiusPacket reply = radiusClient.authenticate((AccessRequest) request, auth, 5);

错误出现:

RadiusPacket reply = radiusClient.authenticate((AccessRequest) request, auth, 5);

有人知道为什么吗？ (我是 JRadius 的新手)( MSCHAPv2Authenticator.java )

在使用 JRadius 库之前，应按如下方式加载 JRadius 字典。

AttributeFactory.loadAttributeDictionary("net.jradius.dictionary.AttributeDictionaryImpl");

此外，请确保您已将 JRadius Dictionary (jradius-dictionary-.jar) 添加到类路径中。
