JHipster 使用 LDAP 认证

Question

我几周前就开始使用 JHipster，从现在开始一切都找到了。我想同时拥有一个 LDAP 身份验证和 JHipster 的默认身份验证。

我关注了这个https://jhipster.github.io/tips/016_tip_ldap_authentication.html，但它没有按计划工作。 实际上我的配置很好地连接到我的 LDAP 服务器，我通过查看日志知道登录搜索到 LDAP 服务器并比较密码。

问题是登录失败并出现错误：

UT005023: Exception handling request to /api/authentication

org.springframework.security.core.userdetails.UsernameNotFoundException: User nseys was not found in the database
    at com.mycompany.myapp.security.PersistentTokenRememberMeServices.lambda$onLoginSuccess$1(PersistentTokenRememberMeServices.java:116)
    at java.util.Optional.orElseThrow(Optional.java:290)
    at com.mycompany.myapp.security.PersistentTokenRememberMeServices.onLoginSuccess(PersistentTokenRememberMeServices.java:116)

    at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
    at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62)
    ...

问题是我希望 JHipster 在数据库中不存在用户时自动在数据库中创建用户并使用参数映射（但仅当它是 LDAP 用户时），如果已经完成则只需连接。

我也搜索了 Spring-security 解决方案，但实现与 JHipster 创建的初始文件相距太远，我不想破坏这一切。

好吧，我尝试了一些可行的方法，我不知道我是否应该这样做，但由于我对此一无所知，而且没有很多文档记录，除非我发现我会坚持使用该解决方案更好的解决方案。

// PersistentTokenRememberMeServices.java

protected void onLoginSuccess(HttpServletRequest request, HttpServletResponse response, Authentication
    successfulAuthentication) {

    String login = successfulAuthentication.getName();

    log.debug("Creating new persistent login for user {}", login);

    PersistentToken t = new PersistentToken();
    t.setSeries(RandomUtil.generateSeriesData());
    t.setTokenValue(RandomUtil.generateTokenData());
    t.setTokenDate(LocalDate.now());
    t.setIpAddress(request.getRemoteAddr());
    t.setUserAgent(request.getHeader("User-Agent"));

    PersistentToken token = userRepository.findOneByLogin(login).map(u -> {
        t.setUser(u);
        return t;
    }).orElse(null);

    if (token == null) {
        if (successfulAuthentication.getPrincipal() instanceof LdapUserDetails) {
            User ldapUser = new User();
            ldapUser.setLogin(login);
            ldapUser.setPassword(RandomStringUtils.random(60)); // We use LDAP password, but the password need to be set
            ldapUser.setActivated(true);

            CustomLdapUserDetails customLdapUserDetails = (CustomLdapUserDetails) successfulAuthentication.getPrincipal();
            ldapUser.setEmail(customLdapUserDetails.getEmail());
            ldapUser.setFirstName(customLdapUserDetails.getFirstName());
            ldapUser.setLastName(customLdapUserDetails.getLastName());

            Set<Authority> authorities = new HashSet<>();
            authorities.add(this.authorityRepository.findOneByName("ROLE_USER"));
            ldapUser.setAuthorities(authorities);
            ldapUser.setLangKey("fr");

            userRepository.save(ldapUser);
            t.setUser(ldapUser);
            token = t;
        } else {
            throw new UsernameNotFoundException("User " + login + " was not found in the database");
        }
    }
    ...
}

我添加了一个 contextMapper 来获取 LDAP 服务器中的属性

// SecurityConfiguration.java
@Bean
public UserDetailsContextMapper userDetailsContextMapper() {
    return new LdapUserDetailsMapper() {
        @Override
        public UserDetails mapUserFromContext(DirContextOperations ctx, String username, Collection<? extends GrantedAuthority> authorities) {
            UserDetails details = super.mapUserFromContext(ctx, username, authorities);
            return new CustomLdapUserDetails((LdapUserDetails) details, ctx);
        }
    };
}

@Inject
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
    LdapContextSource contextSource = new LdapContextSource();
    contextSource.setUrl(applicationProperties.getLdap().getUrl());
    contextSource.setBase(applicationProperties.getLdap().getBase());
    contextSource.setUserDn(applicationProperties.getLdap().getUserDn());
    contextSource.setPassword(applicationProperties.getLdap().getPassword());
    contextSource.afterPropertiesSet(); //needed otherwise you will have a NullPointerException in spring

    auth.ldapAuthentication()
        .userDetailsContextMapper(userDetailsContextMapper())
        .userSearchBase(applicationProperties.getLdap().getSearchBase()) //don't add the base
        .userSearchFilter(applicationProperties.getLdap().getSearchFilter())
        .contextSource(contextSource)
    ;
}
