Impossible to login with new user from Ldap (V5.05)

Hi,

I tried to login with new user from Ldap and have message (in french) "Paramètres de connexion incorrects"
I received mail "L'utilisateur 'jean.dupont' a été créé à partir de Ldap" but it is not created in database.

Below the log Projeqtor:

2015-09-16 16:09:40.737 ***** ERROR ***** ERROR *****
2015-09-16 16:09:40.737 ***** ERROR ***** on file '/pvo/projeqtor/model/User.php' at line (958)
2015-09-16 16:09:40.737 ***** ERROR ***** cause = ldap_bind(): Unable to bind to server: Invalid credentials
2015-09-16 16:09:40.749 ===== TRACE ===== Login error for user 'jean.dupont'

It worked well before updating to v5.05 (it's the first creation of user since updating to V5.05)

Thanks for your help !
