Question

我正在了解Spring Security到LDAP服务器的信息，现在我正在尝试使Spring对ldap服务器进行身份验证。但是，spring始终使用嵌入式服务器ldap://127.0.0.1:33389/dc=springframework,dc=org而不是我的ldap://localhost:389/dc=localdomain,dc=local。我正在尝试使用application.properties对其进行配置，请参见下面的spring配置。

WebSecurityConfig.java

@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    private static final Logger logger = LoggerFactory.getLogger(WebSecurityConfig.class);

    @Autowired
    public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
        logger.info("Loading Global Auth Configuration");
         auth
            .ldapAuthentication();

    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        logger.info("Configuring HTTP Security.");
        // Configure Web Security
        http
            .csrf().disable()
            .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS)
            .and()
            .authorizeRequests()
            .antMatchers("/auth/**").permitAll()
            .anyRequest().authenticated();

        // disable page caching
        http.headers().cacheControl();
    }

    @Override
    public void configure(WebSecurity web) throws Exception {
        logger.info("Configuring Web Security HTTP Security.");
        // AuthenticationTokenFilter will ignore the below paths
        web
            .ignoring()
            .antMatchers(
                HttpMethod.POST,
                "/auth"
            );
    }
}

application.properties

#Ldap Info
spring.ldap.urls=ldap://localhost:389
spring.ldap.anonymous-read-only=true
spring.ldap.username=ldapadm
spring.ldap.password=root123
spring.ldap.base=ou=People,dc=localdomain,dc=local

尝试使用以上application.properties，仍然无法正常工作。

application.properties

#Ldap Info
ldap.urls=ldap://localhost:389
ldap.base.dn=dc=localdomain,dc=local
ldap.username=cn=ldapadm,dc=localdomain,dc=local
ldap.password=root123
ldap.user.dn.pattern =uid={0}

我也尝试了上述属性，但仍然无法正常工作。

对于application.properties中的两个设置，我总是在服务器日志中得到它

有人能理解这些吗？我试图使其读取application.properties，但它在春季始终使用嵌入式ldap

您可以采用与LDAP Authentication with Spring Boot

类似的方法

在application.properties中。

ldap.urls=ldap://localhost:389/dc=localdomain,dc=local

在您的WebSecurityConfig中

 @Value("${ldap.urls:ldap://127.0.0.1:33389/dc=springframework,dc=org}")
  private String ldapUrls;


     @Override
     public void configure(AuthenticationManagerBuilder auth) throws Exception {
     auth
     .ldapAuthentication()
     .userDnPatterns("uid={0},ou=people")
     .groupSearchBase("ou=groups")
     .contextSource()
     .url(ldapUrls)
     .and()
     .passwordCompare()
     .passwordEncoder(new LdapShaPasswordEncoder())
     .passwordAttribute("adminpassword");
     }

请注意，实际参数（userDnPatterns等...）可能会根据您的LDAP配置进行更改，我只是指出了如何配置LDAP配置以连接到外部LDAP
