Symfony 3 api authentication with Ldaptools Jwt and FosUserBundle

Question

I'm trying to auth API and BackOffice users of a Symfony 3 app whith a combination of 3 bundles : LdaptoolsBundle, LexikJwtAuthBundle and fosUserBundle.

Here is my configuration:

config.yml //config.yml

lexik_jwt_authentication:
    private_key_path: %jwt_private_key_path%
    public_key_path:  %jwt_public_key_path%
    pass_phrase:      %jwt_key_pass_phrase%
    token_ttl:        %jwt_token_ttl%

ldap_tools:
    domains:
        company:
        domain_name: ad.company.com
        username: user
        password: password
        servers: ['xxx.xxx.xxx']
        base_dn: 'OU=users, DC=domain'

    security:
        default_role: ROLE_USER

security.yml //security.yml

encoders:
    LdapTools\Bundle\LdapToolsBundle\Security\User\LdapUser: plaintext
    FOS\UserBundle\Model\UserInterface: bcrypt

role_hierarchy:
    ROLE_ADMIN:       ROLE_USER
    ROLE_SUPER_ADMIN: ROLE_ADMIN

providers:
    chain_provider:
        chain:
            providers: [ fos_userbundle, ldap ]
    fos_userbundle:
        id: fos_user.user_provider.username
    ldap:
        id: ldap_tools.security.user.ldap_user_provider

firewalls:
    dev:
        pattern: ^/(_(profiler|wdt)|css|images|js)/
        security: false

    api_login:
        pattern:  ^/api/login
        stateless: true
        anonymous: true
        form_login:
            check_path: /api/login_check
            require_previous_session: false
            username_parameter: username
            password_parameter: password
            success_handler: lexik_jwt_authentication.handler.authentication_success
            failure_handler: lexik_jwt_authentication.handler.authentication_failure
        guard:
            authenticators:
                - ldap_tools.security.ldap_guard_authenticator

    api_secure:
        pattern:   ^/api
        stateless: true
        lexik_jwt:
            authorization_header:
                enabled: true
                prefix:  Bearer
            query_parameter:
                enabled: true
                name:    bearer
        guard:
            authenticators:
                - lexik_jwt_authentication.jwt_token_authenticator
    main:
        anonymous: ~
        provider: chain_provider
        form_login:
            login_path: fos_user_security_login
            check_path: fos_user_security_check
            use_forward: true
        pattern: ^/
        logout: ~
        guard:
            authenticators:
                - ldap_tools.security.ldap_guard_authenticator

    login:
        pattern: ^/login$
        anonymous: ~

access_control:

   - { path: ^/login, roles: IS_AUTHENTICATED_ANONYMOUSLY }
   - { path: ^/api/login, roles: IS_AUTHENTICATED_ANONYMOUSLY }
   - { path: ^/api, roles: IS_AUTHENTICATED_FULLY }
   - { path: ^/, roles: ROLE_USER }

When attempt to login via the login form , everything is OK, I'm authenticate by the Ldap. But when i try to login via the api, only the fosUserBundle Provide is used. No access to Ldap
