JHipster ldap 身份验证

Question

嘿，Overfloweens 和 JHipsters， 我最近得出的结论是，我想尝试将我的 JHipster 安全协议链接到一个 ldap 服务器，以验证我已经拥有所有员工密码和用户名的工作目录中的身份验证。但是，我想继续使用 JHipster 使用 Spring-mvc 的内置令牌系统。我知道除了 JHipster 之外如何做 ldap 服务器，但我不清楚如何修改 SecurityConfiguration.java 文件以使其成为现实。任何建议将不胜感激。

安全配置文件：

Answer 1

默认身份验证机制使用“UserDetailsS​​ervice”实现，在您的项目中应将其称为“com.comcast.castit.security.UserDetailsS​​ervice”。

此代码有一个简单的“loadUserByUsername”，它根据用户的登录名获取用户并获取他的权限。

根据您的需要，您应该更改这部分 -> 这不会影响应用程序的其余部分，这很好（Spring Security 就是为此而设计的）

有一个使用 LDAP 和 Spring Security / Spring Boot 的教程，你可以在这里查看：https://spring.io/guides/gs/authenticating-ldap/

当然，如果我们有 JHipster 的特定文档会更好，所以如果您成功并有时间，我们将非常欢迎您的反馈！

Answer 2

从 SecurityConfig.java 中删除以下代码片段

@Override
@Bean
public AuthenticationManager authenticationManagerBean() throws Exception {
return (AuthenticationManager) ldapAuthenticationManager;
}

然后创建一个 LDAPAuthenticationManager 类

package com.digitronic.isda.security;

import org.springframework.ldap.core.AuthenticationSource;
import org.springframework.ldap.core.support.LdapContextSource;
import org.springframework.security.authentication.AuthenticationManager;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.AuthenticationException;
import org.springframework.security.ldap.DefaultSpringSecurityContextSource;
import org.springframework.security.ldap.authentication.BindAuthenticator;
import org.springframework.security.ldap.authentication.LdapAuthenticationProvider;
import org.springframework.security.ldap.search.FilterBasedLdapUserSearch;
import org.springframework.stereotype.Component;

@Component("authenticationManagerBean")
public class LDAPAuthenticationManager implements AuthenticationManager {


    LdapAuthenticationProvider provider = null;

    @Override
    public Authentication authenticate(Authentication arg0)
            throws AuthenticationException {

        return provider.authenticate(arg0);
    }

    LDAPAuthenticationManager() {

        DefaultSpringSecurityContextSource contextSource = new DefaultSpringSecurityContextSource(
                "ldap://127.0.0.1:389");
        contextSource.setUserDn("test.com\\Administrator");
        contextSource.setCacheEnvironmentProperties(true);
        try {
            contextSource.afterPropertiesSet();
        } catch (Exception e) {

            e.printStackTrace();
        }
        contextSource.setPassword("asdasdasdjBj,K");

        LdapContextSource ldapSrc = new LdapContextSource();
        ldapSrc.setUrl("ldap://127.0.0.1:389");
        ldapSrc.setUserDn("test.com\\Administrator");
        ldapSrc.setPassword("asdasdasdjBj,K");
        ldapSrc.setAnonymousReadOnly(false);
        ldapSrc.setCacheEnvironmentProperties(true);

        try {
            ldapSrc.afterPropertiesSet();
        } catch (Exception e) {
            e.printStackTrace();
        }

        ldapSrc.setAuthenticationSource(new AuthenticationSource() {

            @Override
            public String getPrincipal() {
                // TODO Auto-generated method stub
                return "test.com\\Administrator";
            }

            @Override
            public String getCredentials() {
                // TODO Auto-generated method stub
                return "asdasdasdjBj,K";
            }
        });

        FilterBasedLdapUserSearch userSearch = new FilterBasedLdapUserSearch(
                "cn=Users,dc=digitronic,dc=lan", "(sAMAccountName={0})",
                ldapSrc);

        BindAuthenticator bindAuth = new BindAuthenticator(contextSource);
        bindAuth.setUserSearch(userSearch);
        provider = new LdapAuthenticationProvider(bindAuth);
    }
}

Answer 3

如果你需要一个 UserDetailsContextMapper (For Authorities) 添加这个：

provider.setUserDetailsContextMapper(new UserDetailsContextMapper() {

        @Override
        public void mapUserToContext(UserDetails user, DirContextAdapter ctx) {
            // TODO Auto-generated method stub

        }

        @Override
        public UserDetails mapUserFromContext(DirContextOperations ctx,
                String username,
                Collection<? extends GrantedAuthority> authorities) {

            User anwender = userRepository.findOneByAnwender(username);

            Collection<GrantedAuthority> grantedAuthorities = new ArrayList<>();
            GrantedAuthority grantedAuthority = new SimpleGrantedAuthority(
                    "ROLE_ADMIN");
            grantedAuthorities.add(grantedAuthority);

            return new org.springframework.security.core.userdetails.User(
                    username, "1", grantedAuthorities);
        }
    });

Answer 4

在SecurityConfiguration.java 中将configureGlobal 函数更改为：

@Inject
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
    /*auth
        .userDetailsService(userDetailsService)
            .passwordEncoder(passwordEncoder());*/

    auth.ldapAuthentication()
    .userSearchBase("ou=Users")
    .userSearchFilter("(uid={0})")
    .groupSearchBase("ou=Groups")
    .groupSearchFilter("member={0}")
    .contextSource()
    .url("ldap://127.0.0.1:10389/o=myorganisation");
}

前面的代码我已经注释掉了。 然后您的应用程序将通过您的 ldap 服务器进行身份验证。它仍会检查数据库中的用户详细信息，如果用户表中不存在该用户，您将遇到以下问题： userRepository.findOneByLogin(login) 使用现有用户名在数据库中搜索用户。

但身份验证将使用您的 ldap 凭据进行。

Answer 5

为了使用 LDAP 维护 JHipster 的内置令牌系统，我采用了不同的方法。 每当用户尝试登录时，我都会在 LDAP 服务器中搜索他的凭据，如果存在，则会在本地数据库中使用其 LDAP 属性创建一个新用户，然后所有功能都可以正常工作。

以下类仅用于获取 LDAP 服务器的上下文和用户属性。

public class LDAPHelper {

private static LDAPHelper instance = null;

protected LDAPHelper() {
    // Exists only to defeat instantiation
}

public static LDAPHelper getInstance() {
    if (instance == null) {
        instance = new LDAPHelper();
    }
    return instance;
}

public boolean validateLogin(String username, String password) {
    return (getLdapContext(username, password) != null);
}

private LdapContext getLdapContext(String username, String password) {
    Hashtable<String, String> env = new Hashtable<String, String>();

    env.put(Context.INITIAL_CONTEXT_FACTORY,
            "com.sun.jndi.ldap.LdapCtxFactory");
    env.put("com.sun.jndi.ldap.read.timeout", "120000");
    env.put(Context.SECURITY_AUTHENTICATION, "Simple");
    env.put(Context.SECURITY_PRINCIPAL, "VF-ROOT\\" + username);
    env.put(Context.SECURITY_CREDENTIALS, password);
    env.put(Context.PROVIDER_URL, "*ldap url*");
    System.out.println(username);
    try {
        return new InitialLdapContext(env, null);
    } catch (NamingException e) {
        return null;
    }
}

public User getUserAttributes(String username, String password)
        throws NamingException { ... }

在 AccountResource 中，我更改了 register 方法以在 LDAP 服务器中搜索用户，如果用户存在，我将他添加到本地数据库（如果尚未添加）。 您在登录之前调用此方法以确保只有 LDAP 服务器中的用户才能登录您的应用程序。

     @RequestMapping(value = "/register", method = RequestMethod.POST, produces = { MediaType.APPLICATION_JSON_VALUE,
        MediaType.TEXT_PLAIN_VALUE })
@Timed
public ResponseEntity<?> registerAccount(@Valid @RequestBody ManagedUserDTO managedUserDTO,
        HttpServletRequest request) {

    HttpHeaders textPlainHeaders = new HttpHeaders();
    textPlainHeaders.setContentType(MediaType.TEXT_PLAIN);

    // user exists in LDAP server
    if (LDAPHelper.getInstance().validateLogin(managedUserDTO.getLogin(), managedUserDTO.getPassword())) {

        // user was already created in the local database
        if (userRepository.findOneByLogin(managedUserDTO.getLogin().toLowerCase()).isPresent()) {

            return new ResponseEntity<>("user exists in database", textPlainHeaders, HttpStatus.OK);

        } else {

            try {
                User userAux = LDAPHelper.getInstance().getUserAttributes(managedUserDTO.getLogin(), managedUserDTO.getPassword());                             

                User user = userService.createUserInformation(managedUserDTO.getLogin(), managedUserDTO.getPassword(), userAux.getFirstName(),
                        userAux.getLastName(), userAux.getEmail(), managedUserDTO.getLangKey());                                        

                } catch (NamingException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }

                return new ResponseEntity<>("user created in database", textPlainHeaders, HttpStatus.OK);
            }
        } else {
            return new ResponseEntity<>("user does not exist in ldap", textPlainHeaders, HttpStatus.UNAUTHORIZED);
        }
}
