我有一个使用 LDAP 进行身份验证和授权的 Spring 3 项目。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 权限恢复并正常工作

您需要将内存中的UserDetailsServicebean ( userService) 替换为LdapUserDetailsS​​ervice。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。

userService更详细地说：您当前有一个使用命名空间创建的 bean ：

<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>

你需要用一个看起来像这样的替换它：

<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_" />

但是设置了各种属性以匹配您的目录配置。它们应该类似于您<ldap-authentication-provider>在迁移到 CAS 之前的配置中的任何内容。您还需要声明一个<ldap-server>元素以指向目录服务器。同样，这应该与您以前的情况相匹配。
