【中文标题】使用 CAS 进行身份验证和 LDAP 进行授权的 Spring 项目【英文标题】：Spring project using CAS for Authentication and LDAP for Authorities 【发布时间】：2012-06-26 23:55:20 【问题描述】：我有一个 Spring 3 项目，它使用 LDAP 进行身份验证和授权。我们知道将项目更改为使用 CAS 进行身份验证，但仍然像使用 LDAP 进行授权一样工作。有人可以看看这个 XML 文件并告诉我如何让 LDAP 授权恢复和工作

【问题讨论】：
【参考方案1】：您需要将内存中的UserDetailsService bean (userService) 替换为LdapUserDetailsService。如果您之前使用 LDAP 进行身份验证，那么配置应该几乎相同，假设 CAS 返回的用户名可以轻松映射到目录中。
更详细地说：您当前有一个名为 userService 的 bean，它是使用命名空间创建的：
<user-service id="userService">
<user name="rod" password="rod" authorities="ROLE_SUPERVISOR,ROLE_USER" />
<user name="cpilling04@aol.com.dev" password="testing"
authorities="ROLE_MEMBER_INQUIRY" />
</user-service>
您需要将其替换为如下所示：
<ldap-user-service id="userService"
server-ref="yourLdapServer"
user-search-base="ou=people"
user-search-filter="(uid=0)"
group-search-base="ou=groups"
group-role-attribute="cn"
group-search-filter="(member=0)"
role-prefix="ROLE_" />
但设置了各种属性以匹配您的目录配置。它们应该类似于您在迁移到 CAS 之前在 <ldap-authentication-provider> 配置中的任何内容。您还需要声明一个<ldap-server> 元素以指向目录服务器。这应该与您之前的相同。
【讨论】：
如果您的意思是使用ldap-user-service，详细信息将在很大程度上取决于您的目录是如何设置的。正如我所说，XML 配置属性应该与您之前的类似。如果您搜索，您会找到示例，例如this one。
对不起，我仍然不明白如何将用户服务更改为我的旧 ldap 服务

基于此以及您在网站上发布的其他内容，我最好的猜测是您需要设置group-role-attribute="ou" 而不是使用“cn”。通过使用 LDAP 浏览器查看目录结构，您应该可以轻松解决此问题。以上是关于使用 CAS 进行身份验证和 LDAP 进行授权的 Spring 项目的主要内容，如果未能解决你的问题，请参考以下文章
