【问题描述】：

我正在尝试使用 grails-sporing-security-rest 和 grails-spring-security-ldap 插件对 REST API 实施安全性。

流程应该是这样的，一旦实现了身份验证提供程序，它将使用身份验证机制对用户进行身份验证。

但在我的情况下，我正在尝试验证 JSON 用户名和密码 POST 请求，下面是输出。

如果观察日志，SpringSecurityLDAPTemplate 认证成功，但是当请求进入下一个过滤器 RestAuthenticationFilter 时，它显示 Bad Credentials 错误。这让人有些困惑。 /api/login 是 spring 安全端点，如果认证成功，它将获取用户名和密码，它应该返回适​​当的令牌，但是为什么它又被发送到 RestAuthenticationFilter 呢？

使用正确的用户名和密码：

o.s.security.web.FilterChainProxy        : /api/login at position 1 of 7 in additional filter chain; firing Filter: 'SecurityRequestHolderFilter'

用户名和密码错误：

                    passwordPropertyName: password

更新：

进一步解决了问题，并注意到了这一点。

下面的代码在 SpringSecurityLdapTemplate 类和方法 searchForSingleEntryInternal - 来自 spring-security-ldap 4.2.3 版本。从 ActiveDirectoryLdapAuthenticationProvider 类调用它以从 LDAP 获取信息。

final DistinguishedName searchBaseDn = new DistinguishedName(base);
    final NamingEnumeration<SearchResult> resultsEnum = ctx.search(searchBaseDn,
            filter, params, buildControls(searchControls));

    if (logger.isDebugEnabled()) 
        logger.debug("Searching for entry under DN '" + ctxBaseDn + "', base = '"
                + searchBaseDn + "', filter = '" + filter + "'");
    

    Set<DirContextOperations> results = new HashSet<DirContextOperations>();
    try 
        while (resultsEnum.hasMore()) 
            SearchResult searchResult = resultsEnum.next();
            DirContextAdapter dca = (DirContextAdapter) searchResult.getObject();
            Assert.notNull(dca,
                    "No object returned by search, DirContext is not correctly configured");

在这种情况下 searchResult.getObject 返回 null 导致身份验证失败，但我验证我能够从 resultsEnum 获取属性。

非常感谢任何帮助。谢谢。

【问题讨论】：

您可能不应该在这些 sn-ps 中发布您的密码

同意 Ferdz.. 这实际上是虚拟值而不是原始秘密。

这行代码是 ActiveDirectoryAuthenticationProvider 类的一部分，它正在制造麻烦，因为它期望 LdapContext 对象，实际上它作为 null 传递。扩展 AbstractAuthenticationProvider 并创建自定义身份验证处理程序来解决问题。 DirContextAdapter dca = (DirContextAdapter) searchResult.getObject();
