Spring Security LDAP和数据库角色

Question

我想检查用户名/密码对广告,

Answer 1

你很可能需要做一个定制的UserDetai

<beans:bean id="userDetailsService" class="com.app.MyUserDetailsServiceImpl" />

<authentication-manager>
  <authentication-provider user-service-ref="userDetailsService">
    <password-encoder hash="plaintext" />
  </authentication-provider>
</authentication-manager>

在loadUserByUsername()中，您将创建一个UserDetails，设置用户名、密码和“权限”，即角色。

这篇博客文章有一个关于如何使用数据库的示例，您应该能够根据自己的需求进行调整。

Answer 2

现在实现这一点的最简单的方法(Spring Security 3.2.5.RELEASE)是通过实现一个自html" target="_blank">定义的< code > ldapaauthoritiespoulator ，它使用一个自定义的< code>JdbcDaoImpl从数据库中获取授权。

假设您使用默认的数据库模式，并且在LDAP中使用相同的用户名进行身份验证，并且在< code>authorities表中使用相同的外键，那么您只需要:

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);
    }

}

现在剩下唯一配置LDAP身份验证

在＜code＞配置＜/code＞的注释子类＜code＞全局方法安全配置＜/code＞或＜code＞Web安全配置适配器＜/code＞中，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 */
}

参考https://github.com/pfac/howto-spring-security的例子。

免责声明：我一直只使用Java配置，所以谨慎行事，可能会有一些错误。

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标记来定制< code > ldapaauthoritiespoulator 。所以，必须手动完成。假设已经定义了配置到LDAP服务器的连接的bean contextSource,将以下内容添加到您的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>
