Question

我目前正在尝试使用相互身份验证实现Spring Boot Web服务，该服务需要用户认证，并对用户提供针对ldap服务器的详细信息进行身份验证和授权。

到目前为止，相互认证工作，服务器向用户标识自己并要求提供用户证书。使用内存中用户的示例，整个身份验证和授权过程都可以正常工作。但是，只要我实现LDAP连接，我就会得到“java.lang.IllegalStateException：UserDetailsService是必需的”。例外。有趣的是，当我使用登录页面时，LDAP配置本身工作正常，用户必须手动提示他的凭证。所以简而言之：

登录页面+ LDAP工作，

CERT +内存用户工作，

CERT + LDAP不起作用。

到目前为止，这是我的代码：

web / config / Application.java

    @SpringBootApplication
    @ComponentScan({ "web.*" })

            InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
            viewResolver.setViewClass(JstlView.class);
            viewResolver.setPrefix("/WEB-INF/jsp/");
            viewResolver.setSuffix(".jsp");
            return viewResolver;
        }

                File truststore = new ClassPathResource("cacerts.jks").getFile();
                connector.setScheme("https");
                connector.setSecure(true);
                connector.setPort(8443);

                protocol.setClientAuth("want");
                protocol.setSslProtocol("TLS");

                return connector;
            } catch (IOException ex) {
                 throw new IllegalStateException("can't access keystore: ["
                + "keystore" + "] or truststore: [" + "keystore" + "]", ex);
            }
        }

Answer 1

您必须在web / config / WebSecurity.java文件中添加UserDetailService。

例如

@Override
protected void configure(HttpSecurity http) throws Exception {
    http.authorizeRequests().anyRequest().authenticated()
      .and()
      .x509()
        .subjectPrincipalRegex("CN=(.*?)(?:,|$)")
        .userDetailsService(userDetailsService());
}

@Bean
public UserDetailsService userDetailsService() {
    return new UserDetailsService() {
        @Override
        public UserDetails loadUserByUsername(String username) {
            if (username.equals("Bob")) {
                return new User(username, "", 
                  AuthorityUtils
                    .commaSeparatedStringToAuthorityList("ROLE_USER"));
            }
            throw new UsernameNotFoundException("User not found!");
        }
    };
}

希望如此。

好的，我找到了解决方案。我将Application类重写为：

.
.
.
    public static DefaultSpringSecurityContextSource getSource() throws Exception {

        String address = "ldap://lokalhost:389/dc=ldap";  //example url
        String ldapUser = "cn=admin,dc=ldap";             //example login
        String ldapPassword = "toor";                     //example password

        DefaultSpringSecurityContextSource source = new DefaultSpringSecurityContextSource(
                address);
        source.setUserDn(ldapUser);
        source.setPassword(ldapPassword);
        source.afterPropertiesSet();
        return source;
    }

    @Bean
    public static LdapAuthenticationProvider ldapAuthProvider() throws Exception{

        LdapAuthenticationProvider provider = new LdapAuthenticationProvider(authenticator(),authPopulator()); 

        return provider;
    }


    @Bean
    public static BindAuthenticator authenticator() throws Exception{
        String[] userDn = {"cn={0},dc=users"}; 

        BindAuthenticator auth = new BindAuthenticator(getSource());
        auth.setUserDnPatterns(userDn);
        return auth;

    }
    //authenticator2 only neccessary if authentiction with passwordcompare instead of binduser is wanted.
    @Bean
    public static PasswordComparisonAuthenticator authenticator2() throws Exception{
        String[] userDn = {"cn={0},dc=users"}; 
        PasswordComparisonAuthenticator auth = new  PasswordComparisonAuthenticator(getSource());
         auth.setUserDnPatterns(userDn);
         auth.setPasswordAttributeName("userPassword");
         auth.setPasswordEncoder(Md5Encoder());

         return auth;

    }

    @Bean
    public static DefaultLdapAuthoritiesPopulator authPopulator() throws Exception{

        DefaultLdapAuthoritiesPopulator authPop = new DefaultLdapAuthoritiesPopulator(getSource(),"dc=groups"); 
        authPop.setGroupRoleAttribute("cn");
        authPop.setGroupSearchFilter("(member={0})");
        return authPop;
    }

    //Certificate Authentication
    @Bean
    public static LdapUserDetailsService CustomLdapUserDetailsService() throws Exception{
        LdapUserDetailsService userDetails = new LdapUserDetailsService(userSearch(),authPopulator());
        return userDetails;

    } 
    @Bean
    public static FilterBasedLdapUserSearch userSearch() throws Exception{
        FilterBasedLdapUserSearch search = new FilterBasedLdapUserSearch("","cn={0}",getSource());
        return search;      
    }
}

我也改变了WebSecurityConfig类。现在它看起来像这样：

@Configuration
@EnableWebSecurity
@EnableAutoConfiguration
public class WebSecurityConfig extends WebSecurityConfigurerAdapter  {


    @Autowired
    public void configure(AuthenticationManagerBuilder auth) throws Exception{

        auth.authenticationProvider(Application.ldapAuthProvider());

    }


     @Override
        public void configure(WebSecurity web) throws Exception {
            web
                .ignoring()
                    .antMatchers("/resources/**");
        }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        // *************************************************************************************************
        // Insert pages that need proper authentication/authorization here
        // *************************************************************************************************
        http
        .exceptionHandling().accessDeniedPage("/403")
        .and()
        .x509().subjectPrincipalRegex("CN=(.*?),").userDetailsService(Application.CustomLdapUserDetailsService())
        .and()
        .authorizeRequests()
        .antMatchers("/profile/**").access("hasRole('ROLE_VIEW') or hasRole('ROLE_ADMINISTRATOR')")
        .antMatchers("/welcome**").permitAll()
        .antMatchers("/authenticate").access("hasRole('ROLE_VIEW') or hasRole('ROLE_ADMIN')")
        .antMatchers("/admin").access("hasRole('ROLE_ADMINISTRATOR')")
        .and()
        .formLogin()        
        .and()
        .logout().logoutSuccessUrl("/welcome?logout").logoutUrl("/logout")
        .deleteCookies("JSESSIONID")        
        .and()
        .csrf().disable()

        ;           
    }
}

最后的线索给了我这篇文章： spring-security : Using user's certificate to authenticate against LDAP

我希望我可以帮助那些人。
