[rules-users] Guvnor users and case sensitivity

Hello all, I wonder if I can easily disable the case sensitivity for the user login in guvnor. My users credentials are stored in an LDAP and the server does not ask for case sensitivity. Therefore, for each application, if a user is named "fr001", he can also log as "FR001". But in guvnor, if the administrator create the user "fr001", then, this user will not be able to log as "FR001" even if he is successfully authenticated. Guvnor returns the error "This user has no permissions setup.". Can we easily disble this, please ? Regards, Régis Ramillien
