我使用的是Spring Security 5.7，WebSecurityConfigurerAdapter已弃用。我想使用多个身份验证提供程序（LDAP和Dao），但LDAP提供程序不工作，Spring Security只调用DaoAuthenticationProvider。

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class SecurityConfiguration {

@Autowired
private JWTTokenFilter jwtTokenFilter;

@Autowired
private LdapAuthProvider ldapAuthProvider;

@Autowired
private UserService userService;

@Bean
public DaoAuthenticationProvider authenticationProvider() {
    DaoAuthenticationProvider authProvider = new DaoAuthenticationProvider();
    authProvider.setUserDetailsService(userService);
    authProvider.setPasswordEncoder(passwordEncoder());
    return authProvider;
}

@Bean
public SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception {
    http
            .cors()
            .and().csrf().disable()
            .headers().frameOptions().disable()
            .and().sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS)
            .and().authorizeRequests().antMatchers("/api/test/**", "/auth/**", "/h2-console/**").permitAll()
            .and().authorizeRequests().anyRequest().authenticated()
            .and().addFilterBefore(jwtTokenFilter, UsernamePasswordAuthenticationFilter.class);
    http.authenticationProvider(ldapAuthProvider);
    http.authenticationProvider(authenticationProvider());
    return http.build();
}

@Bean
public AuthenticationManager authenticationManager(
        AuthenticationConfiguration authenticationConfiguration) throws Exception {
    return authenticationConfiguration.getAuthenticationManager();
}

@Bean
public PasswordEncoder passwordEncoder() {
    return new BCryptPasswordEncoder();
}

@Bean
public CorsFilter corsFilter() {
    UrlBasedCorsConfigurationSource source =
            new UrlBasedCorsConfigurationSource();
    CorsConfiguration config = new CorsConfiguration();
    config.setAllowCredentials(true);
    config.addAllowedOrigin("*");
    config.addAllowedHeader("*");
    config.addAllowedMethod("*");
    source.registerCorsConfiguration("/**", config);
    return new CorsFilter(source);
}

}

当删除DaoAuthenticationProvider时，LdapAuthProvider将正常工作。问题是什么？
编辑：我希望在整个应用程序中使用公开AuthenticationManager，如下所示：

@Autowired
private AuthenticationManager authenticationManager;

@PostMapping("/login")
public ResponseEntity<?> login(@RequestBody AuthRequest authRequest) {

    if(authRequest.getUsername() == null || authRequest.getPassword() == null) {
        return ResponseEntity.badRequest().build();
    }

    Authentication authenticate = null;
    try {
        authenticate = authenticationManager.authenticate(new UsernamePasswordAuthenticationToken(
                authRequest.getUsername(),
                authRequest.getPassword()));
    } catch (Exception e) {

        e.printStackTrace();
        return ResponseEntity.status(401).build();
    }

但此身份验证管理器不包含我自定义身份验证提供程序
