Java – Why are all the Spring boot actuator endpoints publicly available

I have Spring Security on my classpath (and verified working for my own REST controllers), yet my Actuator endpoints are all publicly available by default (except for /shutdown).

I can disable endpoints as I please (after reading through this question), but enabled ones are always available without authentication and without the role required by management.security.role in my properties.

Even when I explicitly set endpoints.beans.sensitive=true for instance, it's still accessible without authentication.

My Security configuration which uses LDAP for authentication:

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
    @Autowired
    private LdapContextSource contextSource;

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth
                .ldapAuthentication()
                .contextSource(contextSource)
                .groupRoleAttribute("<hidden>")
                .groupSearchBase("<hidden>")
                .groupSearchFilter("<hidden>")
                .userDnPatterns("<hidden>");
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.httpBasic();
    }
}

My application.properties during this test:

# Log4J properties
logging.file=${user.home}/nubis-log.log
logging.level.org.springframework.web=INFO
logging.level.org.hibernate=INFO
logging.register-shutdown-hook=true

# SSL configuration
server.ssl.key-store=<hidden>
server.ssl.key-store-password=<hidden>
server.ssl.keyStoreType=<hidden>
server.ssl.key-password=<hidden>

# Spring actuator
endpoints.enabled=false
endpoints.info.enabled=true
endpoints.health.enabled=true
endpoints.beans.enabled=true
endpoints.beans.sensitive=true
management.security.role=ADMIN

My console output:

Could there be a configuration/property blocking Spring Security somewhere? Do I need to configure something extra to make it work with LDAP?
