Question

我正在尝试使用grails-sporing-security-rest和grails-spring-security-ldap插件为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。

但是在我的情况下，我正在尝试验证JSON用户名和密码POST请求，以下是输出。

如果您观察到日志，则SpringSecurityLDAPTemplate身份验证成功，但是当请求转到下一个过滤器RestAuthenticationFilter时，它将显示Bad Credentials错误。这令人有些困惑。 / api / login是spring安全性端点，如果身份验证成功，它将使用用户名和密码，它应该返回适当的令牌，但是为什么又将其发送到RestAuthenticationFilter？

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：

更新：

进一步解决了问题，并注意到了这一点。

下面的代码行位于 SpringSecurityLdapTemplate 类和方法 searchForSingleEntryInternal 中-从spring-security-ldap 4.2.3版本开始。从 ActiveDirectoryLdapAuthenticationProvider 类中调用该类以从LDAP中获取信息。

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返回的null导致身份验证失败，但是我验证了自己能够从resultsEnum获取属性。

我们非常感谢您的协助。谢谢。

Answer 1

这行代码是ActiveDirectoryAuthenticationProvider类的一部分，正在引起麻烦，因为它期望LdapContext对象的传递实际上为null。扩展了AbstractAuthenticationProvider并创建了自定义身份验证处理程序来解决该问题。

DirContextAdapter dca = (DirContextAdapter) searchResult.getObject();
