LDAP Authorization: No mapping role when test role are OK.

Hi,

i'm trying to update my LDAP configuration to 7.x-1.0-beta3 to 7.x-2.0-beta3 in order to populate OG groups via LDAP, but I have some problems with the role mapping.

My configuration :

Settings :
HTTPS : Yes
Log detailed : Yes
Servers :
Type : Open LDAP
Binding method : Service account bind
User :
Reject manual creation
Any LDAP Servers providing provisioning data
Authentification :
Mixed
Autorization :
Enable
Only apply : No
Only grant : Yes
Mapping : cn=...,ou=...,ou=...,dc=...,dc=...|administrator (with ..., values of my LDAP)
Grant/revoke when a user logs on : Yes
3 latest actions : Yes

When I test my configuration in Authorization drupal_role test, Drupal gives me the good answer but when this same person try to connect on the site, it has not the roles which it should have.

Do you have an idea ?

I precise that all works good with my previous LDAP version and the same parameters.

Thanks to your help.
