Thanks for your helping me, but it doesn't solve my problem. because when the auth tables trying to define i receive this error:
Can't create table 'myDB.auth_membership' (errno: 150) and i think this errors raised because of the `auth_membership.user_id` is depend on the ID column of my users table which is not `id` as i said it's `userid`. and i don't think we can solve the problem, because i looked at Tools.py and i see the `id` column is a static string and not optional. i just should hack the core code and i don't think it's a good idea!!
