HibernateMembershipModuleImpl won't be able to resolve user/role relationship in such scenario and I suspect this is the root of exception during login process. So simply you cannot mix modules in such way. Only usage of delegating UserProfileModule for DB is allowed - like configured in default ldap config. Sory if documentation wasn't clear enough about this. I will add a note there. If you'll have any other issues don't hesitate to ask.
