java集成微软的ad域，实现单点登录

1.ad域介绍：

windos server 2008R2服务器下的ad域，见下图（我是在虚拟机安装到windos server）

2.连接ad域代码：（里面代码自行修改）

public ResultMsg<User> loginAd(User user) throws Exception {
        ResultMsg<User> msg;
        //通过ad域登录
        Hashtable env = new Hashtable();
        env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
        //ad域地址：windos server上输入ipconfig查看，369是固定端口，dc=contoso,dc=com是域的范围
        env.put(Context.PROVIDER_URL, "ldap://192.168.153.160:389/dc=contoso,dc=com");
        //ad域里面的用户
        env.put(Context.SECURITY_PRINCIPAL, "admin@contoso.com");
        //ad域里面的密码
        env.put(Context.SECURITY_CREDENTIALS, "Ai123456");
        DirContext ctx = null;

        String st="";
        try {
            //登录验证
            ctx = new InitialDirContext(env);
            SearchControls controls = new SearchControls();
            controls.setSearchScope(SearchControls.SUBTREE_SCOPE);
            //根据用户名查看ad域中是否存在当前用户
            results = ctx.search("", "(&(objectclass=person)(userprincipalname=" + user.getUsername()+domainName + "))", controls);
            SearchResult searchResult = (SearchResult) results.next();
            Attributes attributes = searchResult.getAttributes();
            if (attributes != null) {
