具有过滤器、验证器、支持 spring-security等。仅限 Windows,但不需要本机 DLL。

Has filters, authenticators, supports spring-security, etc. Windows-only, but doesn't require native DLLs.

说实话,你不应该寻找一个。 为了满足您的 SSO 需求,您应该使用适当的 kerberos / SPNEGO 而不是旧版 NTLM。

对于这些东西,您不需要特殊的库,因为 JVM 已经可以自动执行此操作。 您所要做的就是正确配置应用程序和 JVM 安全策略。 Sun 的官方文档应该为您提供所需的所有详细信息,只需浏览“安全 API”部分即可。

To be honest, you should not look for one. For your SSO needs you should use proper kerberos / SPNEGO instead of the legacy NTLM.

For that stuff you need no special libraries as JVMs are already enabled for doing that automatically. All you have to do is to configure your application and JVM security policies properly. The official documentation from Sun should give you all the details you need, just browse the "security APIs" section.

实际上 jcifs 很好,您可以轻松测试 4 次握手 在本地与 Windows IIS 和保持活动的 java 套接字。

这个 2004 Apache 伪代码对于使用 generateType1Msg()generateType3Msg() 构建 jcifs 算法非常有用,甚至 Apache 也推出了 示例 作为 HttpClient 的替代方案。

2004 年的旧 Apache 代码可以工作,但身份验证不稳定,您经常会收到 HTTP/1.1 401 Unauthorized ,还有这个 来自 Luigi Dragone 的非常旧的代码不再工作了。 另一方面,Apache 的 HttpClient 运行平稳,但握手是在幕后完成的(仅供参考。HttpClient 需要 new NTCredentials() 来定义用户的身份验证)。

下面是在 IIS 上本地测试握手的示例,端口 81 上没有域。 您需要适当地更改 hostportuserpassword 以及 HTTP 标头,最终 WWW -如果您不使用 IIS,请进行身份验证

HTTP/1.1 200 OK 表示身份验证正确,否则您将得到 HTTP/1.1 401 Unauthorized

Actually jcifs is good and you can test easily the 4-way handshake locally with Windows IIS and a keep alive java Socket.

This 2004 Apache pseudo code is useful to build the algorithm with jcifs using generateType1Msg() and generateType3Msg(), even Apache promotes an example as an alternative to HttpClient.

The old Apache code from 2004 works but authentication is unstable, you get HTTP/1.1 401 Unauthorized frequently, also this really old code from Luigi Dragone does not work anymore. On the other hand Apache's HttpClient runs smoothly but the handshake is done behind the scene (fyi. HttpClient requires new NTCredentials() to define user's authentication).

Here's an example to test the handshake locally on IIS, on port 81 without a domain. You need to change the host, port, user and password and HTTP headers appropriately, eventually WWW-Authenticate if you are not using IIS.

HTTP/1.1 200 OK means the authentication is correct, otherwise you get HTTP/1.1 401 Unauthorized.

我认为 NTLM 已被弃用,取而代之的是 Kerberos/SPNEGO。 查看 SPNEGO HTTP Servlet Filter 项目,看看它是否适合您的需求。

I think NTLM is being deprecated in favor of Kerberos/SPNEGO. Take a look at the SPNEGO HTTP Servlet Filter project to see if it might fit your needs.

Java 开源单点登录 (JOSSO) 位于 http://www.josso.org/
他们有一个关于 NTLM 的页面,尽管我不确定它的效果如何。

Java Opensource Single Sign On (JOSSO) is at http://www.josso.org/
They have a page on NTLM, although I'm not sure how well it works.

如果您不介意商业包装产品,请查看:Quest Single Sign On for Java,提供对 SPNEGO/Kerberos(包括站点和 S4U 协议)以及 NTLM 的支持。

If you don't mind a commercially packaged product then take a look at: Quest Single Sign On for Java which provides support for SPNEGO/Kerberos (including sites and S4U protocols) as well as NTLM.
