A token was not found in the Security Context

[ylcdx]

Hi,

I've this Exception after authentification : "A token was not found in the Security Context"

My config.yml :

opensky_ldap:
client:
host: ldap.mysite.com
port: 382
username: "admin"
password: ************
useStartTls: false
useSsl: false
accountDomainName: mysite.com
accountDomainNameShort: mysite
baseDn: "CN=Users,DC=mysite,DC=com"
user_base_dn: ou=Utilisateurs,ou=DSI,dc=mysite,dc=com
user_filter: (objectClass=user)
username_attribute: uid
role_base_dn: ou=Groupes,ou=DSI,dc=mysite,dc=com
role_filter: (objectClass=role)
role_name_attribute: cn
role_user_attribute: memberuid
security:
role_prefix: ROLE_LDAP_
default_roles: [ROLE_USER, ROLE_LDAP]

My security.yml

security:
acl:
connection: default
factories:
- %kernel.root_dir%/../vendor/bundles/OpenSky/Bundle/LdapBundle/Resources/config/security_factories.xml
providers:
ldap:
id: opensky_ldap.user_provider
firewalls:
backend:
provider: ldap
pattern: ^/
http_basic_pre_auth: true
stateless: true
access_control:
- { path: ^/, roles: IS_AUTHENTICATED }

I must create my UserToken? or is it a bug?
