具有 LDAP 和数据库角色的 Spring Security

Question

在我们的新保险项目中，我正在尝试实现 spring-security使用 Ldap active-directory .

一旦用户在 AD 中找到，我想仅检查 AD 中的用户名/密码。我想从用户表(应用程序授权用户)中授权他具有数据库中的访问级别。有人可以提供示例/给我指出一个好的资源吗？

Answer 1

现在实现这一点的最简单方法(Spring Security 3.2.5.RELEASE)是通过实现自定义的LdapAuthoritiesPopulator，它使用自定义的JdbcDaoImpl从数据库。

代码

假设您正在使用the default database schema ，并且您在 LDAP 中使用相同的用户名进行身份验证并作为 authorities 表中的外键，您只需要这样:

package demo;

import java.sql.ResultSet;
import java.sql.SQLException;
import java.util.Collection;
import java.util.List;

import org.springframework.jdbc.core.RowMapper;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.authority.AuthorityUtils;
import org.springframework.security.core.authority.SimpleGrantedAuthority;
import org.springframework.security.core.userdetails.User;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import org.springframework.security.core.userdetails.jdbc.JdbcDaoImpl;

import org.springframework.ldap.core.DirContextOperations;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.ldap.userdetails.LdapAuthoritiesPopulator;

/*
 * You need to extend JdbcDaoImpl to expose the protected method loadUserAuthorities.
 */
public class CustomJdbcUserDetailsService extends JdbcDaoImpl {

    @Override
    public List<GrantedAuthority> loadUserAuthorities(String username) {
        return super.loadUserAuthorities(username);
    }
}


/*
 * Then, the only thing your populator needs to do is use the custom UserDetailsService above.
 */
public class CustomLdapAuthoritiesPopulator implements LdapAuthoritiesPopulator {

    private static final Logger LOGGER = LoggerFactory.getLogger(CustomLdapAuthoritiesPopulator.class);

    private CustomJdbcUserDetailsService service;

    public CustomLdapAuthoritiesPopulator(CustomJdbcUserDetailsService service) {
        this.service = service;
    }

    public Collection<? extends GrantedAuthority> getGrantedAuthorities(DirContextOperations user, String username) {
        return service.loadUserAuthorities(username);
    }

}

现在剩下的唯一一件事就是配置 LDAP 身份验证提供程序以使用 CustomLdapAuthoritiesPopulator。

Java 配置

在 GlobalMethodSecurityConfiguration 或 WebSecurityConfigurerAdapter 的 @Configuration 带注释的子类中(根据您的情况)，添加以下内容:

@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {

    /* other authentication configurations you might have */

    /*
     * This assumes that the dataSource configuring
     * the connection to the database has been Autowired
     * into this bean.
     *
     * Adapt according to your specific case.
     */
    CustomJdbcUserDetailsService customJdbcUserDetailsService = new CustomJdbcUserDetailsService();
    customJdbcUserDetailsService.setDataSource(dataSource);

    CustomLdapAuthoritiesPopulator customLdapAuthoritiesPopulator = new CustomLdapAuthoritiesPopulator(customJdbcUserDetailsService);

    auth.ldapAuthentication().ldapAuthoritiesPopulator(customLdapAuthoritiesPopulator)/* other LDAP configurations you might have */;

    /* yet more authentication configurations you might have */
}

引用https://github.com/pfac/howto-spring-security一个工作示例。

XML 配置

免责声明:我一直只使用 Java 配置，因此请谨慎行事，可能会出现一些错误。

与使用 LDAP 进行身份验证的其他配置不同，似乎没有漂亮的 XML 标记来自定义 LdapAuthoritiesPopulator。因此，必须手动完成。假设已定义配置 LDAP 服务器连接的 bean contextSource，请将以下内容添加到 Spring XML 配置中:

<beans:bean id="customJdbcUserDetailsService" class="demo.CustomJdbcUserDetailsService" />
<beans:bean id="customLdapAuthoritiesPopulator" class="demo.CustomLdapAuthoritiesPopulator">
    <beans:constructor-arg ref="customJdbcUserDetailsService" />
</beans:bean>

<beans:bean id="ldapAuthProvider" class="org.springframework.security.ldap.authentication.LdapAuthenticationProvider">
    <beans:constructor-arg>
        <beans:bean class="org.springframework.security.ldap.authentication.BindAuthenticator">
            <beans:constructor-arg ref="contextSource" />
            <!--
                other configurations you might need
            -->
        </beans:bean>
    </beans:constructor-arg>
    <beans:constructor-arg ref="customLdapAuthoritiesPopulator" />
</beans:bean>

<security:authentication-manager>
  <security:authentication-provider ref="ldapAuthProvider" />
</security:authentication-manager>
